A monatomic ideal gas at 1.65 atm and an initial temperature of25.0 °C undergoes a slow expansion at constant pressure from a volume of 2.25x10-3 m3 to 3.25x10-3 m3.
1. Find the work done on the gas by the surrounding environment.
2. Discover the change in internal energy of the gas during this process.
3. Decide the thermal energy absorbed by the gas during this process.
