Let's say a gas started with 200 joules of internal energy and while you add 180 joules of heat to the gas, the gas does 70 joules of work. What is the final internal energy of the gas? All right, so the change in internal energy equals Q. Let's see, gas starts with 200 joules of internal energy, that's not heat.
