Question

How can you plan an investigation using water, a glass, and a bucket to demonstrate that thermal energy is not the same as temperature?

a) Pour hot water into the glass and measure the change in temperature over time.
b) Fill the bucket with cold water and measure the temperature.
c) Fill the glass with hot water and observe how long it takes to cool down in the bucket of cold water.
d) Fill the bucket with water and measure the change in thermal energy.

Answer 1

To plan an investigation using water, a glass, and a bucket to demonstrate that thermal energy is not the same as temperature, you can pour hot water into the glass and measure the change in temperature over time, fill the bucket with cold water and measure the temperature, or fill the glass with hot water and observe how long it takes to cool down in the bucket of cold water.

Step-by-step explanation:

To plan an investigation using water, a glass, and a bucket to demonstrate that thermal energy is not the same as temperature, you can:

1. Pour hot water into the glass and measure the change in temperature over time.
2. Fill the bucket with cold water and measure the temperature.
3. Fill the glass with hot water and observe how long it takes to cool down in the bucket of cold water.

Option (d) Fill the bucket with water and measure the change in thermal energy is not necessary in this specific investigation. By carrying out the experiments described in options (a), (b), and (c), you can observe that although the temperature may change, the total thermal energy of the system remains constant.
