GENERAL KNOWLEDGE

Detailed explanation-1: -There are three ways heat is transferred into and through the atmosphere: radiation. conduction. convection.

Detailed explanation-2: -Radiation is responsible for most of the heat transferred into the room. Heat transfer also occurs through conduction into the room, but at a much slower rate. Heat transfer by convection also occurs through cold air entering the room around windows and hot air leaving the room by rising up the chimney.

Detailed explanation-3: -The overall direction of heat transfer is from the higher-temperature object to the lower-temperature object.

Detailed explanation-4: -Advection. Conduction. Convection. Convection vs. conduction. Radiation.
