Paige turns on an electric space heater in the center of her bedroom. the coils glow, and the room becomes warmer. how is heat reaching the corners of paige’s bedroom?
a. by conduction and convection
b. by conduction and radiation
c. by radiation and convection
d. by radiation only

The right option is; c. by radiation and convection

Heat is reaching the corners of Paige’s bedroom by radiation and convection.

Convection is a process by which heat is transmitted by movement of a heated fluid such as air or water, while radiation is the transfer of energy (such as heat) in the form of particles or waves through space or through a substance. From the question, the coil (heating element) in the electric space heater is surrounded by a fluid (water or oil). The fluid is heated by the coil and the fluid carries the heat energy and reaches the surrounding air by radiation and convection.
