 During an experiment an ideal gas is found to obey an additional law V2P = constant. The gas is initially at temperature T and volume V. When it expands to a volume 2V, the temperature becomes

a
T
b
2T
c
T2
d
T2

detailed solution

Correct option is D

PV = RT (ideal gas equation)---------(i)V2P = C(additional law)-----------(ii)Dividing V = CRT ⇒ V ∝1Tor T = 1V  (combined law)When volume (V) is doubled, temperature is halved i.e., T' = T2

For one-mole ideal gas, a process follows the relation P=V2V2+V02P0, where P0 and V0 are constants. If the volume the gas changes from V0 to 2V0. What is the change in temperature?
