Temperature of gas rises
How do you calculate work done from The area under the graph
a P- V graph?
What is efficiency? the percentage of the work input that becomes useful work output
What is thermal equilibrium? when two objects have the same temperatures and net heat transfer is zero
The change in a system's internal energy is equal to the difference
