Josh did an experiment, recording the changes in temperature in sand and water when exposed to a light source, and then when the light source was removed. Josh decides that

B sand conducts heat better than water.sand conducts heat better than water.

C water conducts heat better than sand.water conducts heat better than sand.

D neither sand nor water conducts any heat.

Answer 1

To determine whether Josh's conclusion about the heat conduction of sand and water is valid, we would need to evaluate the results of his experiment. From general scientific knowledge:

• Sand typically has a lower specific heat capacity than water, meaning it can heat up and cool down more quickly.
• Water has a higher specific heat capacity, allowing it to absorb more heat without a large change in temperature.

Given these properties, if Josh observed that sand reached a higher temperature faster and cooled down quicker compared to water when exposed to the same light source, it would be logical for him to conclude that:

B: sand conducts heat better than water.

This conclusion is consistent with the properties of sand and water in relation to heat transfer.
