Question

As an experiment, Bertie made wax candles. He used a heat transfer process to melt the wax in a pot on the stove. Throughout the process, Bertie observed that the wax changed from a solid to a liquid state. What type of heat transfer process did Bertie use to melt the wax?

1) Conduction
2) Convection
3) Radiation
4) Evaporation

Answer 1

Bertie used 1) conduction to melt the wax on the stove, which is the transfer of heat through direct physical contact.

Step-by-step explanation:

The heat transfer process Bertie used to melt the wax in a pot on the stove is known as conduction. Conduction is the transfer of heat through stationary matter by physical contact. In Bertie's experiment, heat was transferred from the stove burner through the bottom of the pot and into the wax causing it to change from a solid to a liquid state, highlighting a physical change in the wax. This process was facilitated by the direct contact between the pot and the heat source (stove burner).
