Question

johnny is conducting an investigation on heat transfer. he recorded the initial temperature of a metal block. he then placed the metal block under a heat lamp. after 2 minutes, he recorded the final temperature of the metal block. he found that the temperature increased 4 degrees. which explanation accurately explains the increase in temperature? a the block absorbed electromagnetic waves from the light which decreased the temperature of the block. b the block absorbed heat by the collision of atoms. c the block absorbed electromagnetic waves from the light which increased the temperature of the block. d the block absorbed heat due to the rising and sinking of atoms.

Explanation:

Light is a form of electromagnetic wave. When a metal block is placed under a heat - lamp, it absorbs electromagnetic waves (light) which increases its temperature. Heat transfer via electromagnetic waves is called radiation.

Answer:

B. The block absorbed electromagnetic waves from the light which increased the temperature of the block.
