Will the volume of a gas increase, decrease, or remain unchanged for the following set of changes? The pressure is decreased from 6.33 atm to 1.05 atm, while the temperature...

Question

is increased from 123 degrees C to 234 degrees C

a) The volume increased

b) The volume will decrease

c) The volume will not change

Answer 1

In this situation, you are changing BOTH the pressure (P) and the temperature (T) and asked what will happen to the volume (V).

If only the pressure is decreased, the volume will increase.

If only the temperature is increased, the volume will increase.

So, if both the pressure and temperature increase, the volume will increase.
