One mole of an ideal gas passes through a process where pressure and volume obey the relation P=Po1-12VoV2. HerePoandVoare constants. Calculate the change in the temperature of the gas if its volume changes fromVo to 2Vo.

Options:

Answer:
B
Solution:

For ideal gas,PV=nRT
Therefore,nRTV=P01-12V0V2
 T=P0VR1-12V0V2
Therefore, the change in temperature is:
ΔT=Tf-Ti
=P02V0R1-12V02V02-P0VR1-V022V02
=5P0V04R
