14 (a) For 1.0 mol of a monatomic ideal gas taken through the cycle in Fig. 20-24, where V₁ = 4.00V, what is W/poVo as the gas goes from state a to state c along path abc? What is AEint/PoVo in go- ing (b) from b to c and (c) through one full cycle? What is AS in going (d) from b to c and (e) through one full cycle?

Suppose 3.32 moles of a monatomic ideal gas expand adiabatically, and its temperature decreases from 371 to 254 K. Determine (a) the work done (including the algebraic sign) by the gas, and (b) the change in its internal energy.

A balloon holding 4.50 moles of oxygen (0,) gas absorbs 935 J of thermal energy while doing 112 J of work expanding to a larger volume. HINT (a) Apply the first law of thermodynamics. (b) Recall that the molar specific heat at constant volume, C, takes different values depending on whether the gas is monatomic or diatomic. Click the hint button again to remove this hint. (a) Find the change in the balloon's internal energy (in J). (b) Calculate the change in temperature of the gas (in K). K

A gas is at initial conditions of pressure 1 atm and temperature of 300k. We compress the gas adiabatically to a final pressure of 10 atm. Calculate the temperature in the final state assuming in the cases in the gas a) air; b) helium
