Final answer:
The second type of heat transfer is convection, which occurs when heat is transferred by the movement of a fluid. The third type is radiation, which involves the transfer of heat through electromagnetic waves. Examples of convection include hot air rising above a heater, while radiation can be felt from the sun's rays.
Step-by-step explanation:
The second type of heat transfer is convection. Convection is the transfer of heat by the movement of a fluid, such as a gas or a liquid. When a fluid is heated, it becomes less dense and rises, creating a convection current. This allows heat to be transferred from one place to another. An example of convection is when hot air rises above a heater and spreads throughout a room.
Radiation is the third type of heat transfer. Radiation occurs when heat is transferred through electromagnetic waves, such as light or infrared waves. Unlike conduction and convection, radiation does not require direct contact or a medium to transfer heat. An example of radiation is the warmth you feel from the sun's rays on a sunny day.
