A)a sample of gas expands from a volume of 2.00 m3 at a pressure of 3.0x105 pa to a volume of 5.00 m3 at a pressure of 1.5x105 pa. how much work is done by the gas if it first expands at constant pressure, then its pressure is decreased at constant volume? how much work is done by the gas if its pressure is first decreased at constant volume, then it is allowed to expand at constant pressure? b)what are the heat capacities at constant volume and at constant pressure of one mole of an ideal diatomic gas? c)2.00 m3 of a diatomic ideal gas initially at a temperature of 293 k is compressed adiabatically and reversibly from a pressure of 1.00 x 104 pa to 6x that pressure. what are the final volume and temperature of the gas? d)argon may be considered to be an ideal, monatomic gas with 3 degrees of freedom. a sample of 10.3 moles of argon initially occupies a volume of 0.250 m3 at a pressure of 1.00 x 105 pa and temperature of 292 k. the sample is isothermally compressed to one-fifth of its original volume what is the change in entropy of the gas? e)the specific heat capacity of granite is 796 j k-1 kg-1. how much energy is required to raise the temperature of 4.0 kg of granite from 14 c to 30 c? (assume no heat losses).
