A gas has experienced a small increase in volume but has maintained the same pressure and number of moles. According to the ideal gas law, how has the temperature of the gas changed?

Verified Answer :

ccahill

temperature has increased

Ideal Gas Law:

pressure volume = (number of moles of gas) (0.08206) * (temperature)

or short-hand:
PV = nRT

this equation can be transformed to solve for temperature as:
T = PV / nR

given there is no change in pressure and the volume of the container has increased, we know the temperature increases because volume is in the numerator--a larger number on top reflects an overall greater number.

B) It has increased slightly
