Heat and Thermal ExpansionHard
Question
A gas expands such that its initial and final temperature are equal. Also, The process followed by the gas traces a straight line on the P - V diagram :-
Options
A.The temperature of the gas remains constants throughout.
B.The temperature of the gas first increase and then decrease
C.The temperature of the gas first decrease and then increase.
D.The straight line has a negative slope.
Solution
Let V0 = intial volume = 2V0 = final volume
V = volume of any state
then
⇒ nRT = PV = V
∴ T - V curve is a parabola with vertex above.
Hence temperature first increase then decrease
