Question

Under constant pressure a sample of hydrogen gas initially at 88°C and 9.6 L is cooled until its final volume is 3.4 L. What is the final temperature?

Answer 1

The final temperature = -145.24K or 127°C.

According to the data given,

T1= 88°C = 361.15K

V1= 9.6 L

V2= 3.4 L

T2= ?

We know that, according to Charles's law,

T1/V1=T2/V2

T2= T1*V2/V1

T2= 127°C or -145.24K

The final temperature = -145.24K or 127°C

What does Charles law state?

According to Charles' law, when the pressure is held constant, the volume of a given amount of gas is precisely proportional to its temperature on the kelvin scale.

What connection exists between volume and temperature?

• In layman's words, the volume of a fixed mass of gas is exactly proportional to temperature at constant pressure.
• When a constant mass of gas is cooled, its volume decreases, and when the temperature is elevated, its volume grows.

What are the applications of Charles law?

• A hot air balloon drifting through the air is an illustration of Charles Law in action.
• The air within the balloon is heated by a torch, which causes the air molecules to move more quickly and disperse.
• This causes the air inside the balloon to be less dense than the air outside, which causes the balloon to float.
