Finally, the age of the urine will affect the chemical composition. Rancid urine has much more free ammonia, and ammonium salts, and a lot less urea than a fresh sample. Now, let us assume that the person is normal and drinks good amount of water, so the freezing point will be around -5 degree centigrade.

Re: At what temperature does human blood freeze? Blood, which is a mix of many components, both cellular and chemical, behaves like many other salty (saline) solutions and freezes at between -2 to -3 degrees celsius.
Is it true that under very low temperature, one's urine will turn into ice as soon as he/she peed? When tested in a freezer at −70 °F (−57 °C) the fake urine stream the MythBusters used did not freeze in midair. However, spit is known to freeze since it is mostly water.
There's A Reason You Have To Pee More In Cold WeatherScientists have dubbed this phenomenon "cold-induced diuresis," which basically means an increase of urine caused by the cold. However, when it's cold outside, your kidneys have more blood to filter than normal because there's more blood pumping through your body.
Well, gasoline freezes at -100ºF or below, depending on what exactly its mixture of liquid components is (octane freezes earlier than that). But just because gasoline won't freeze in your car doesn't mean a low gas tank won't be harmed by cold temperatures.
Death by cold is harder to delimit. A person usually expires when their body temperature drops to 70 degrees F (21 degrees C), but how long this takes to happen depends on how "used to the cold" a person is, and whether a mysterious, latent form of hibernation sets in, which has been known to happen.
Though space is typically very cold -- most floating objects have a surface temperature of -454.8 degrees Fahrenheit -- a person would not instantly freeze because heat does not transfer away from the body very quickly.
YSK: What is the highest temperature a human being can survive
- Dry air: 120+ °C (248+ °F) short term, 70+ °C (158+ °F) long term (with access to water at cooler temperatures).
- Tropical air: 60+ °C (140 °F) short term, 47 °C (117 °F) long term.
- Saturated air: 48 °C (118 °F) short term, 35 °C (95 °F) long term.
- Water: 46° C (115 °F) short term, 41°C (106 °F) long term.
The record for the lowest body temperature at which an adult has been known to survive is 56.7 F (13.7 C), which occurred after the person was submerged in cold, icy water for quite some time, according to John Castellani, of the USARIEM, who also spoke with Live Science in 2010.
As you probably know, space is already very, very cold — roughly 2.7 Kelvin (-270.45 Celsius, -454.81 Fahrenheit). This is mostly due to a lack of atmosphere and the vacuum-like nature of space — with very few molecules to energetically bounce around, there can be no heat.
How cold does it have to be to freeze gasoline in fuel lines? How do I prevent that from happening? Gasoline will freeze somewhere between -40C and -70C. You are highly unlikely to encounter any temperatures of these kinds.
Heatstroke is a condition caused by your body overheating, usually as a result of prolonged exposure to or physical exertion in high temperatures. This most serious form of heat injury, heatstroke, can occur if your body temperature rises to 104 F (40 C) or higher.
Originally Answered: At what temperature does blood freeze? LMGTFY: Human blood freezes at -2 to -3 degrees Celsius. No, the blood vessels on the side of your face didn't freeze-that's nearly impossible until you are dead or so near dead it doesn't matter.
Yes, and you can take a pee anywhere in Antarctica (or even the Arctic). Despite it being very cold at times, that area of the body is very well supplied with blood vessels, and for the time it takes nothing should freeze.
Turns out a dogs normal body temperature is around 102 °F. So, safe to say so is their pee. The urine did not freeze.
The freezing point of urine depends on the concentration of urine, which depends on the quantity of salts, urea, and various other organic substances present. Now, let us assume that the person is normal and drinks good amount of water, so the freezing point will be around -5 degree centigrade.
When that happens, your blood pressure will rise, because the same volume of blood is flowing through less space in your body. In response, your kidneys will pull out excess fluid to reduce your blood pressure, making you have to pee.
Freezing Urine For A Drug Test. The main things to keep in mind when freezing the urine sample is to do it as soon as possible. Ideally, it should go straight into the freezer after exiting the body. This is because bacteria quickly start growing in the urine once it comes in contact with our surrounding air.
Simply: the body lets less warmth out, and less cold in, and one way to do that is by not allowing blood into colder places. To regulate that, your kidneys move to pull liquid out of the body, which leads to more liquid in your bladder than there would normally be. Sup, pee.
Shivering is an involuntary response to coldness. And if you're like some people, you may experience something known as “pee shivers,” either after urinating or during the release of urine. This weird phenomenon is unofficially called post-micturition convulsion syndrome.
Most people urinate between six and eight times a day. But if you're drinking plenty, it's not abnormal to go as many as 10 times a day. You may also pee more often if you're taking certain medications, like diuretics for high blood pressure.
Urine is usually warm. Noticing that urine feels warm or hot is perfectly normal. Urine may feel especially warm if a person's body or hands are cold. However, if a person notices that their urine feels warmer than usual, or hot as it comes out of the urethra, this may mean that there is an infection or injury.
Cold diuresis is the body's way of preserving heat when it feels that you may be in danger of hypothermia. When your body begins to react to a drop in temperature, it starts to constrict your blood vessels to reduce blood flow to the skin and keep the warmth around your internal organs.
Urinary tract infection (UTI)A UTI is another more common cause of cloudy or milky urine. The cloudy look typically comes from discharge of either pus or blood into the urinary tract. It could also be a buildup of white blood cells as the body tries to eliminate invading bacteria.
It must be frozen in a cryogenic freezer. For all of you who doesn't know what a cryogenic freezer is it's liquid nitrogen. The longer you freeze the fart the more pressure will build up in your fart can and/or container. So don't let anybody tell you a fart can't be frozen because it can.
Condensation – Condensation can form in the empty part of your gas tank. In the winter that condensation can freeze, collect into icy blockages in your fuel lines and create problems with starting your car. The best way to avoid this happening is to keep your tank more than half full during the winter.
But if a car battery is discharged because of damage to cells, poor connections or a charging system that isn't doing its job, the battery could start freezing at the same temperature as water at 32 degrees Fahrenheit. “A 100 percent fully charged battery will not freeze until approximately minus 76 degrees Fahrenheit.
Like a wine without a cork, gas can go bad when it sits around mingling with air. Fuel actually starts to turn nasty after 30 days. Since your car's fuel system is not an airtight container, precautions have to be taken for long-term storage. The easy solution is an additive called a fuel stabilizer.
The freezing point of the fuel must always be lower than the minimum operational tank temperature. Jet A is the most common type of aviation fuel in the USA. The freezing point specification for Jet A is -40 degrees F. Typical Jet A freezing points are -55 degrees F to -40 degrees F.
It's chilly in Britain right now, but spare a thought for the residents of Oymyakon, Russia, widely recognised as the coldest inhabited place on Earth. How cold is it? Right now it's a relatively balmy −44°C. That's some way off its record, −67.8°C, the lowest ever reading outside Antarctica.
Lohud chatted with local and national car experts about what you should do to help prevent your vehicle from becoming another casuality of the cold.
- Get those small cracks fixed.
- Check your tires.
- Warm up your car — but not for too long.
- Take care of your wipers and battery.
- Keep a full tank of gas.
Ethanol and Freezing Point DepressionThis phenomenon is known as freezing point depression. It is possible to freeze vodka, but not in a typical home freezer. The freezing point of 80 proof vodka is -26.95 C or -16.51 F, while the temperature of most home freezers is around -17 C.
