1. a radiator contains hot coils that touch the surrounding air. identify two types of heat transfer involved in radiator heating, and mark the places on the diagram where the kinetic energy of the air particles is highest and lowest.
Answer
# Answer:
The two types of heat transfer are conduction and convection. The place with the highest kinetic - energy of air particles is near the radiator, and the place with the lowest kinetic - energy of air particles is near the cold floor.
# Explanation:
## Step1: Identify heat transfer types
Conduction occurs when the hot coils of the radiator transfer heat directly to the adjacent air molecules. Convection occurs as the heated air near the radiator rises, creating a convection current in the room.
## Step2: Determine kinetic - energy locations
The air near the radiator is heated, so the air particles have more kinetic energy. The air near the cold floor is cooler, so the air particles have less kinetic energy.
