# Given a jar of gas (fixed volume and pressure) at 273.15K, the temperature is lowered to 0K, what happens to the volume?

The volume remains the same

#### Explanation:

Charles' Law, or the law of volumes, was found in 1787 by Jacques Charles. It states that, for a given mass of an ideal gas at constant pressure, the volume is directly proportional to its absolute temperature, assuming in a closed system.

As a mathematical equation, Charles' Law is written as

Now solve;

So since you haven't provided a volume initial i cant give u the exact number

But we do know that with a decrease in temp. the volume will decrease and vice versa

But here there is no piston to keep the volume down
