A figure shows a gas doing 180 J of work and its internal energy increasing by 320 J. How much heat enters the gas?
The figure shows 400 J of heat added to a gas and 400 J of work done by the gas. What is the change in internal energy?
A gas absorbs 450 J of heat from a flame and does 300 J of work on the surroundings. Taking an increase as positive, what is ΔU?
A gas gives 200 J of heat to the surroundings while 90 J of work is done on the gas. What is the change in internal energy?
