Question

(a) Determine the pressure (in atm), temperature (in ?C) and volume (in cm3) of the gas at points 1, 2, and 3. Put your results in a table. Hint: Use the ideal gas law to determine p1.

(b) How much work is done on the gas during each of the three segments?
(c) How much heat energy is transferred to or from the gas during each of the three segments?

The figure above shows a thermodynamic process followed by 120mg of Helium. Note: Helium is a monatomic gas. (a) Determine the pressure (in atm), temperature (in ?C) and volume (in cm3) of the gas at points 1, 2, and 3. Put your results in a table. Hint: Use the ideal gas law to determine p1. (b) How much work is done on the gas during each of the three segments? (c) How much heat energy is transferred to or from the gas during each of the three segments?

Explanation / Answer

The number of moles of helium is
n = m/M = 120
