An electric heater supplies heat to a system at a rate of 100 W. If the system performs work at a rate of 75 J/s, then the rate at which internal energy increases will be:

Solution & Explanation

Related Formula
(dQ)/(dt) = (dU)/(dt) + (dW)/(dt)
Core Logic
100 W = (dU)/(dt) + 75 W ⇒ (dU)/(dt) = 25 W
Pattern Recognition

Rate form of the First Law of Thermodynamics.
