Question

1.) Calculate the work needed for a bird of mass 120 g go to fly a height of 50 m from the surface of the earth.

2.) A sample of 1.00 mol of perfect gas molecules with Cp = 7/2 R is put through the following cycle: (a) constant volume heating to twice its initial volume, (b) reversible adiabatic expansion to its initial temperature, (c) reversible isothermal compression back to 1.00 atm. Calculate the Q, W, dU, and dH for each step and overall.
