Here is a more detailed explanation of the process:
1. When you turn on the electric heater, the electricity flows through a heating element inside the heater.
2. The heating element heats up and starts to emit infrared radiation.
3. The infrared radiation from the heating element travels through the air and strikes objects in the room, such as walls, furniture, and people.
4. These objects absorb the infrared radiation and convert it into heat.
5. The heated objects then release heat into the surrounding air, raising the temperature of the room.
A small amount of heat is also lost through the body of the heater itself. This is because the heater is not perfectly insulated, and some of the heat it generates escapes through its body. However, the majority of the heat produced by the heater stays in the room.
