Question

An ideal gas is expanding such that PT3= constant. The coefficient of volume expansion of the gas is:

Choose an option

Show full solutionCorrect option: D
Correct answer
D4T

Step-by-step explanation

γ=1VdVdt

PT3= constant

TVT3= Constant

T4 V-1=C

V-14 T3 dT+T4-1 V2 d V=0

dVdT=4T3/VT4/V2=4VT  ∴γ=4T
