In a process the pressure of gas is inversely proportional to the square of the volume. If temperature of the gas is increased than work done by the gas

a
Is positive
b
Is negative
c
Is zero
d
May be positive

detailed solution

Correct option is B

P α1v2⇒P=KV2⇒PV2=K   PV.V=K⇒nRTV=K⇒TV=K1 Since temperature increase therefore volume decreasestherefore work done is negative

An ideal gas undergoes a process in which PVa= constant, where Vis the volume occupied by the gas initially at pressure P. At the end of the process, rms speed of gas molecules has become a1/2 times of its initial value. What will be the value of CV so that energy transferred by the heat to the gas is 'a'times of the initial energy (ΔQ=aPV)
