Question

how can we protect pups paws?

1. when the dog boot is placed on the hot pavement, why does the boot heat up?

thermal energy is destroyed as it leaves the pavement
thermal energy is transported from the air to the pavement
thermal energy transfers from the pavement to the boot
thermal energy is created at the surface between the pavement and the boot

Explanation:

Thermal energy transfer occurs from a hotter object to a cooler one. Here, the pavement is hot and the boot is cooler. According to the law of conservation of energy, energy is not created or destroyed (so options with energy creation or destruction are wrong). Also, the question is about transfer from pavement to boot, not air to pavement.

Answer:

Thermal energy transfers from the pavement to the boot.
