An ideal gas with pressure P, volume V and temperature T is expanded isothermally to a volume 2V and a final pressure `P_i`, If the same gas is expanded adiabatically to a volume 2V and a final pressure `P_alpha` find the value of ratio `P_alpha/P_i`. The ratio of the specific heats for the gas is 1.67.

A litre of hydrogen at 27^@C and 10^5 Nm^-2 pressure expand isothermally until its volume is doubled and then adiabatically until its volume is redoubled. Find the final pressure of the gas. 1(gamma = 1.4)

A gas expands adiabatically at constant pressure such that T propV^(-1//2) The value of gamma (C_(p,m)//C_(v,m)) of the gas will be :

Two gases A and B having same preesure P, volume V and temperature T are mixed. If mixture has volume and temperature as V and T respectively . Then pressure of the mixture wil be:

One mole of an ideal gas (C_(v,m)=(5)/(2)R) at 300 K and 5 atm is expanded adiabatically to a final pressure of 2 atm against a constant pressure of 2 atm. Final temperature of the gas is :

Consider two containers A and B containing identical gases at the same pressure, volume and temperature. The gas in container A is compressed to half of its original volume isothermally while the gas in container B is compressed to half of its original value adiabatically. The ratio of final pressure of gas in B to that of gas in A is

An inflated rubber ballon contains one mole of an ideal gas, has a pressure p, volume V and temperature T. If the temperature rises to 1.1 T, and the volume is increase to 1.05 V, the final pressure will be

An ideal gas undergoes isobaric expansion at pressure P from volume V_1 to V_2 the work done is :

10 litre of a non linear polyatomic ideal gas at 127^(@)C and 2 atm pressure is suddenly released to 1 atm pressure and the gas expanded adiabatically against constant external pressure. The final temperature and volume of the gas respectively are.

If at 50^@C and 75 cm of mercury pressure , a definite mass of a gas is compressed slowly, then what will be the final pressure and temperature of the gas if the final volume is one-fourth of the initial volume?
