Question

A chair is placed several feet from a fireplace. The fireplace has a glass screen. The side of the chair

facing the fireplace gets warm because of
a) Conduction
b) Convection
c) Radiation
d) Touching

Answer 1

The chair gets warm because of radiation from the fireplace.

Step-by-step explanation:

The correct answer is c) Radiation.

In this scenario, the chair gets warm because of radiation. Radiation is the transfer of heat energy in the form of electromagnetic waves. In this case, the heat from the fireplace is emitted as infrared radiation, which travels through the air and is absorbed by the chair, causing it to warm up.

Conduction, on the other hand, is the transfer of heat through direct contact. Convection is the transfer of heat through the movement of fluids, such as air or water.

Answer 2

No the first one is wrong because the fire “Radiates” the energy and warms of the side of the chair, and the glass is in the way
