Question

question 9 of 10
which type of thermal energy transfer warms your hand when you hold it near a glass of hot water?
a. radiation
b. transportation
c. convection
d. conduction

Explanation:

Radiation is the transfer of energy by electromagnetic waves. Convection involves the movement of fluids. Conduction is the transfer of heat through direct contact. When you hold your hand near a glass of hot water, the heat transfer is mainly through radiation as there is no direct contact (ruling out conduction) and no significant fluid - movement between your hand and the glass in the context of this question (ruling out convection). Transportation is not a type of thermal energy transfer.

Answer:

A. Radiation
