One mole He gas at 300K, 10 atm is heated through a process in which its pressure is directly propotional to square of its absolute temperature becomes 600 K. The change in entropy of He is :

One mole of an ideal monoatomic gas at 1 atm, 300 K undergo a process in which pressure of gas is 8 atm then calculate W (in cal).

One mole of a diatomic ideal gas at 300 K is heated at constant volume until its pressure is doubled and then expanded adiabatically till its temperature falls to 300K. The work done by the gas is, if R is molar gas constant:

One mole of SO_(2) at 298K and 1atm pressure is heated in a closed vessel so that its temperature is 475K and pressure is 4atm . It is then cooled so that temperature becomes 298K and pressure is 1atm . What is that change in the internal energy of the gas?
