Question

Which improves air circulation in forced-air heating?


radiation

conduction

convection

Answer 1

Convection improves air circulation in forced-air heating. In a forced-air heating system, warm air is distributed throughout a space by blowing it through ducts, which creates airflow. This airflow helps to circulate the warm air effectively, utilizing the principles of convection as warmer air rises and cooler air is drawn in to be heated.
