Solution

False. The material of the surface does affect the rate at which an object transfers energy by heating. Different materials have different thermal conductivities, which is a measure of how quickly they can transfer heat. For example, metals generally have high thermal conductivities and can transfer heat quickly, while materials like wood or plastic have lower thermal conductivities and transfer heat more slowly.
