Below is a table showing the temperatures of some objects and their surroundings. Which object's thermal energy store will increase? B C A Object & }(c) Temperature of object (( )^circ mathrm(C)) & Temperature of surroundings (( )^circ mathrm(C)) A & 90 & 30 B & 10 & 18 C & 60 & -12

Answer 1

## Step 1: Identify the temperatures of the objects and their surroundings from the table. - Object A: \(T_{\text{object}} = 90^\circ \text{C}\), \(T_{\text{surroundings}} = 30^\circ \text{C}\) - Object B: \(T_{\text{object}} = 10^\circ \text{C}\), \(T_{\text{surroundings}} = 18^\circ \text{C}\) - Object C: \(T_{\text{object}} = 60^\circ \text{C}\), \(T_{\text{surroundings}} = -12^\circ \text{C}\) ## 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: \(T_{\text{object}} > T_{\text{surroundings}}\) (90°C > 30°C), so thermal energy will transfer from Object A to the surroundings. - Object B: \(T_{\text{object}} < T_{\text{surroundings}}\) (10°C < 18°C), so thermal energy will transfer from the surroundings to Object B. - Object C: \(T_{\text{object}} > T_{\text{surroundings}}\) (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. #
