During an adiabatic process,the pressure of a gas is found to be proportional to 4 power of its absolute temperature.The gamma for the gas is

Options

A. 1
B. 1.33
C. 1.67
D. 1.4

Answer

B

Explanation

`P^3 prop 1/V^4 implies P^3 V^4 =` constant
` impliesPV^(4//3)` =constant
Comparing with PV.
`implies gamma = 4/3 =1.33`
