Introduction:
In this experiment, we will fill one black can and one white can with the same amount of water and at the same initial temperature. We will then leave both cans in a room or shade and observe the change in temperature after 10-15 minutes. The objective is to determine if the temperature of water in both cans falls by the same amount.

Explanation:
The color of an object affects how it interacts with light. When light strikes an object, it can be absorbed, transmitted, or reflected. The color of an object is determined by the wavelengths of light that are reflected.

1. Absorption of Light:
- Darker colors, such as black, absorb more light.
- Lighter colors, such as white, reflect more light.

2. Heat Transfer:
- Heat is transferred through a process called conduction, where energy is transferred from areas of higher temperature to areas of lower temperature.
- Darker colors absorb more heat energy from sunlight or any other source of heat radiation.
- Lighter colors reflect more heat energy and do not absorb as much.

3. Experiment Setup:
- Fill one black can and one white can with the same amount of water at the same initial temperature.
- Place both cans in the same room or shade.

4. Observations:
- After 10-15 minutes, measure the temperature of water in both cans.
- It is expected that the temperature of water in the black can will decrease more compared to the white can.
- This is because the black can absorbs more heat energy from the surroundings, including any heat radiation present in the room or shade.

5. Conclusion:
- The temperature of water in the black can will fall by a greater amount compared to the white can.
- This is due to the difference in heat absorption between the two colors.
- The black can absorbs more heat energy, resulting in a greater decrease in temperature.
- The white can reflects more heat energy, leading to a smaller decrease in temperature.

Note:
It is important to consider that various factors can affect the temperature change, such as the initial temperature of the water, the surrounding temperature, and the duration of the experiment. It is recommended to repeat the experiment multiple times and take an average to obtain more accurate results.
