Physics

The pV diagram in (Figure 1) shows a cycle of a heat engine thatuses 0.250 mole of an ideal gas having γ=1.10. The curved part abof the cycle is adiabatic. The internal energy of the gas changesby the following amounts: ΔUa→b=−2220J, ΔUb→c=−1.06×104J, andΔUc→a=+1.29×104J. c=(0.002, 1.5) b=(0.009, 1.5)

Part A: Find the pressure of the gas at point a.

Express answers in pascals to three significant figures.

Part B: How much heat enters this gas per cycle?

Express your answer in joules to three significant figures.

Part D: How much heat leaves this gas in a cycle?

Express your answer in joules to three significant figures.

Part F: How much work does this engine do in a cycle?

Express your answer in joules to three significant figures.
