Question

a watermelon is at a temperature of 31°c. then the watermelon is cut in half. select the better estimate for the temperature of each smaller piece of watermelon. 13°c 31°c

Explanation:

Step1: Analyze the effect of cutting

Cutting the watermelon into halves doesn't change its internal temperature as temperature is an intensive property (doesn't depend on amount of substance).

Step2: Compare the options

The original temperature is \(31^\circ\text{C}\), so the temperature of each half should still be close to \(31^\circ\text{C}\), not \(13^\circ\text{C}\) (which is a significant drop without a cooling process).

Answer:

\(31^\circ\text{C}\)
