An ideal gas with pressure P, volume V and temperature T is expanded isothermically to a volume 2V and a final pressure P_i, If the same gas is expanded adiabatically to a volume 2V, the final pressure P_a. The ratio of the specific heats of the gas is 1.67. The ratio (P_a)/(P_1) is .......

An ideal gas with pressure P, volume V and temperature T is expanded isothermally to a volume 2V and final pressure P_(I) . The same gas is expanded adiabatically to a volume 2V and final pressure in this case is P_(A) . In terms of the ratio of the two specific heats for the gas gamma , the ratio P_(I)//P_(A) is

An ideal gas of volume V and pressure P expands isothermally to volume 16 V and then compressed adiabatically to volume V . The final pressure of gas is [ gamma = 1.5]

Initial pressure and volume of a gas are P and V respectively. First it is expanded isothermally to volume 4 V and then compressed adiabatically to volume V. The final pressure of gas will be (given gamma=(3)/(2) )

When an ideal gas at pressure P, temperature T and volume V is isothermally compressed to V/n. its pressure becomes P_i . If the gas is compressed adiabatically to V/n, its pressure becomes P_a . The ratio P_i//P_a is: ( l = C_P //C_V )

A monatomic gas at a pressure P, having a volume V expands isothermally to a volume 2 V and then adiabatically to a volume 16 V. The final pressure of the gas is ( take gamma=5/3 )
