A gas in a cylinder expands from a volume of 0.150 m^3 to 0.390
m^3 . Heat flows into the gas just rapidly enough to keep the
pressure constant at 1.90×10^5 Pa during the expansion. The total
heat added is 1.15×10^5 J a)Find the change in internal energy of
the gas.

When the gas expands at constant pressure 180 Pa, the increase
in volume is 1.5 m3 and the heat lost by the gas 300J. Evaluate the
change in internal energy?

To practice Problem-Solving Strategy 19.1 The First Law of
Thermodynamics. A 3.00 mol sample of carbon dioxide undergoes a
two-step process. First, at a constant volume, the gas behaves
ideally as it is cooled from 39.0 ?C to -78.5 ?C where it reaches a
pressure of 1 atm. Second, at -78.5 ?C and a constant pressure of 1
atm the gas undergoes a phase change to dry ice. What is the change
in internal energy of carbon dioxide for this...
