A gas mixture consists of 2.0 moles of oxygen and 4.0 moles of neon at temperature T. Neglecting all vibrational modes, calculate the total internal energy of the system.(Oxygen has two rotational modes.)

Calculate the least amount of work that must be done to freeze one gram of water at 0 ^@ C by means of the refrigerator.The temperature of the surrounding is 27 ^@ C .How much heat is passed on the surrounding in this process? Latent heat of fusion L=80 cal/g.

A welding fuel gas contains carbon and hydrogen only. Burning a small sample of it in oxygen gives 3.38 g carbon dioxide, 0.690g of water and no other products. A volume of 10.0L (measured at STP) of this welding gas is found to weigh 11.7 g. Calculate molar mass of the gas
