What is the work done by the gas?
What is the temperature of the gas after the expansion?
How many moles of the gas’s molecules are contained in the gas?
What is the change in the internal energy of the gas?
By how much is the gas heated?
1.000 mole of a dilute diatomic gas occupies a volume of 12.00 L. The gas expands against a constant pressure of 1.150 atm when it is slowly heated. If the temperature of the gas rises by 18.70 K and it is heated with 609.5 J, what is the gas’s final volume?
Find the work done by the gas.
Find the amount of heating of the system.
