In a closed insulated container, a liquid is stirred with a paddle to increase the temperature, which of the following is true?
- ΔE = W, q = 0
- ΔE = W + q = 0
- ΔE = 0, W = q ≠ 0
- W = 0, ΔE = q ≠ 0
Correct answer: ΔE = W, q = 0
Solution
In a closed insulated container, the system is isolated from its surroundings, so q = 0.
