Question

Disuss what happened at each station and how heat was transferred (or was not transferred) when objects were wrapped in towels or exposed directly to the skin.

Answer 1

When students held the object directly, heat passed from the warmer object to the cooler skin through direct contact; this is conduction. The towel acted as an insulator and slowed the heat transfer, so the object felt less hot through the towel. The amount of heat transferred also depended on the object’s material and temperature.
