It is found experimentally that the amount of heat transfer per unit mass required to heat a gas from (10% C) to (4OM C) at constant pressure is (21.85 kJ/kg). similarly, the amount of heat transfer to raise the temperature of (5.5 kg) of the same gas from (7 C) to (170 C) at constant volume is found to be (28.62kJ) Assume that the gas is ideal and that the specific heat value are constant. Calculate the value of [cv, cp, and gama ratio].

A cylinder of cross-section area A is divided into two chambers 1 and 2, by means of a frictionless piston. The chambers initially have equal length L. Both chambers are filled with 1 mole of ideal gas, wlth initial pressures M 2Po and Po, respectively. The piston is then allowed to slide freely, whereupon the gas in chamber 1 pushes the piston a distance 1 to equalize the pressure. Consider the following two cases: m (i) The outer walls of the chambers and the piston do not w w mw m allow heat transfer. Denote the distance l as la in this case. (ii) The piston does not allow heat transfer but the chambers are in contact with two heat reservoirs w ww separately, at temperature Tl and T2 for chambers 1 and 2, respectively. Denote the distance 1 as ld in this case. Calculate the ratio la/ld ? Does this ratio have a small or big vala
