Question 30 • LHS Physical Science

Which best compares radiation and conduction?

Answer
A
Both transfer thermal energy from warm objects to cooler objects.
B
Both can transfer energy through empty space.
C
Both transfer thermal energy by electromagnetic waves.
D
Both involve the transfer of energy through direct contact.

Explanation

Both radiation and conduction transfer thermal energy from warmer objects or regions to cooler ones. Radiation transfers energy by electromagnetic waves and can travel through empty space, while conduction transfers energy through direct contact between particles. Therefore, the best comparison is that both move thermal energy from warm to cool.
