Questions  

One mole of an ideal gas at temperature  T1 expand according to the lawp/v=constant. Find the work done when the final temperature become T2:  
 

a
RT2−T1
b
R2T2−T1
c
R4T2−T1
d
PVT2−T1

detailed solution

Correct option is B

W=∫v1v2 PdV=∫v1v2 VdV∴W=12kv22−v12PV=RT But P=kv∴kv2=RT Or kv22−v12=RT2−T1W=R2T2−T1
