For ideal gas, PV = nRT
Molecular weight of He = 4 g/mol
Weight of He = 130 mg = 0.13g
n = Number of moles of ...
The expert determines the temperature of the gas at different points.
See attached diagram.
1. The figure shows a thermodynamic process followed by 150mg of helium.
a) Determine the pressure (in atm) of the gas at points 1, 2, and 3.
b) Determine the temperature (in celsius) of the gas at points 1, 2, and 3.
c) Determine the volume (in centimeters cubed) of the gas at points 1, 2, and 3.
V1,V2,V3=_________ centimeters cubed
d) How much work is done on the gas during each of the three segments?
e) How much heat energy is transferred to or from the gas during each of the three segments?
