## Will a real gas ever reach absolute zero will an ideal gas ever reach absolute zero Why or why not?

It appeared that an “ideal gas” at constant pressure would reach zero volume at what is now called the absolute zero of temperature. Any real gas actually condenses to a liquid or a solid at some temperature higher than absolute zero. Therefore, the ideal gas law is only an approximation to real gas behaviour.

## What happens to ideal gas at absolute zero?

Theoretically, at absolute zero the volume of an ideal gas would be zero and all molecular motion would cease. In actuality, all gases condense to solids or liquids well above this point. At such low temperatures, gases assume nontraditional states, the Bose-Einstein and fermionic condensates.

## Has absolute zero ever been reached?

Absolute zero cannot be achieved, although it is possible to reach temperatures close to it through the use of cryocoolers, dilution refrigerators, and nuclear adiabatic demagnetization. The use of laser cooling has produced temperatures less than a billionth of a kelvin.

## What will happen if we reach absolute zero?

Absolute zero is often thought to be the coldest temperature possible. At the physically impossible-to-reach temperature of zero kelvin, or minus 459.67 degrees Fahrenheit (minus 273.15 degrees Celsius), atoms would stop moving. As such, nothing can be colder than absolute zero on the Kelvin scale.

## What is the coldest external temperature a human can survive?

The average body temperature is 98.6 degrees Fahrenheit. At an internal temperature of 95 degrees, humans can experience hypothermia, shivering and pale skin. At 86 degrees, they become unconscious and, at 77 degrees, cardiac arrest can occur. Most people cannot survive if their core temperature drops to 75 degrees.

## How cold is too cold for recess?

Most schools that experience cold or extreme cold climates will cancel recess when the temperature is at 32 degrees. The 32-degree marker is the freezing point. This is when most people can start to develop frostbite.

## At what temperature should a child wear a winter coat?

40-50 degrees: Child must wear a jacket. 30-40 degrees: Child must wear a winter jacket, hat and mittens.

## Is it safe to run in below freezing temperatures?

Any temperature below 32 degrees can lead to freezing injuries such as frostbite and non-freezing injuries such as hypothermia. Runners should consider changing to an indoor training activity when temperatures fall below zero degrees and should not perform outdoor training when temperatures fall below -20 degrees.

## Is 25 degrees too cold to run?

A good rule of thumb to follow is that if it’s -20 degrees Fahrenheit (wind chill included), stay inside at all costs. If it’s between that and 25 degrees F, running can be done with proper precautions for cold weather, but if you have a medical condition, you should check with your doctor before suiting up.

## Why does running hurt my lungs?

However, when you are outside working hard (e.g., running) and you are breathing a lot harder, those cells that line the trachea become severely dehydrated. Once dehydrated they become irritated, and you perceive this dehydration and irritation as “burning” in your throat and lungs.

## Should you cover your mouth when running in the cold?

When it gets very cold outside and it’s windy, it’s a good idea to cover your mouth and nose, especially you aren’t used to working out in the cold. Covering your mouth and nose will help warm the air moving to your lungs so it will be more comfortable to breath.

## Is it better to run in the cold or heat?

Yet many runners might find it easier than running in hot weather. That could be because lower temperatures reduce stress on the body. When you run in cold weather, your heart rate and the body’s dehydration levels are lower than in warmer conditions.

## Does jogging give abs?

Plus, “running is a great cardiovascular form of exercise, which in return is one of the best ways of reducing body fat levels, and thus help in making your abs more visible.”
