Question

the diagram below shows two rooms that are at different temperatures.

which statement best describes what will happen if the door opens between the two rooms?

a. the temperature in both rooms will become equal over time.

b. the temperature in each room will remain unchanged.

c. the colder room will warm up to 80°f.

d. the warmer room will cool down to 50°f.

Explanation:

Step1: Analyze heat transfer

Heat flows from warmer to cooler areas. When the door opens, heat will transfer between the two rooms.

Step2: Determine temperature change

The warmer room (\(80^{\circ}F\)) will lose heat and cool down, and the cooler room (\(50^{\circ}F\)) will gain heat and warm up. Over time, their temperatures will equalize.

Answer:

A. The temperature in both rooms will become equal over time.
