Answer
Object B
Explanation
## Step 1: Identify the temperatures of the objects and their surroundings from the table.- Object A:
,
- Object B:
,
- Object C:
,
## Step 2: Determine the direction of thermal energy transfer for each object.- Thermal energy transfers from a higher temperature to a lower temperature.## Step 3: Analyze each object:- Object A:
(90°C > 30°C), so thermal energy will transfer from Object A to the surroundings.- Object B:
(60°C > -12°C), so thermal energy will transfer from Object C to the surroundings.## Step 4: Identify which object's thermal energy store will increase.- Only Object B has a lower temperature than its surroundings, meaning it will gain thermal energy from the surroundings.#
