1. Two clouds are about the same size. One appears light in colour and the other appears dark because it blocks more sunlight. Which would be a better heat sink? Why?

..would the darker one be a better heat sink?; because it gets heat more.

black. because a black color absorbs more energy than a white object (or because white reflects more energy than black).

Yes, the darker cloud would be a better heat sink because it absorbs more sunlight and therefore gets hotter. As a heat sink, it is able to absorb and store more thermal energy, making it more effective at dissipating heat.

To determine which cloud would be a better heat sink, we need to understand the concept of albedo. Albedo refers to the measure of reflectivity of a surface. Surfaces with high albedo reflect more sunlight, while surfaces with low albedo absorb more sunlight.

In this case, the cloud that appears darker has a lower albedo as it absorbs more sunlight, while the lighter cloud has a higher albedo and reflects more sunlight. Therefore, the darker cloud would be a better heat sink because it absorbs more heat from the sunlight.

To further explain how to answer this question, you can consider the following steps:

1. Understand the concept of albedo: Albedo is the measure of reflectivity of a surface. Surfaces with low albedo absorb more sunlight and thus heat up more, while surfaces with high albedo reflect more sunlight and stay cooler.

2. Compare the colors of the clouds: Determine which cloud appears darker and which appears lighter. The darker cloud would have a lower albedo and absorb more sunlight, while the lighter cloud would have a higher albedo and reflect more sunlight.

3. Determine the heat sink: Based on the understanding of albedo, the cloud that appears darker would be a better heat sink since it absorbs more heat from the sunlight.

4. Explain the reason: The reason why the darker cloud is a better heat sink is that it absorbs more sunlight, which leads to more heat being trapped within the cloud. Meanwhile, the lighter cloud reflects more sunlight and absorbs less heat, making it a less effective heat sink.

By following these steps, you can understand and explain why the darker cloud would be a better heat sink in this scenario.
