If the temperature of an object increases, what happens to the rate of heat radiation from that object?
Decreases
Increases
Remains constant
Becomes zero
According to Stefan-Boltzmann law, the rate of heat radiation increases with the fourth power of the temperature, so as the temperature increases, the rate of radiation also increases.

Q
Q: If the temperature of an object increases, what happens to the rate of heat radiation from that object?
Solution: According to Stefan-Boltzmann law, the rate of heat radiation increases with the fourth power of the temperature, so as the temperature increases, the rate of radiation also increases.
Steps: 5
Step 1: Understand that heat radiation is the energy emitted by an object in the form of infrared radiation.
Step 2: Know that the temperature of an object is a measure of how hot it is.
Step 3: Learn about the Stefan-Boltzmann law, which states that the amount of heat radiation emitted by an object increases with temperature.
Step 4: Realize that the rate of heat radiation increases not just a little, but by a factor related to the fourth power of the temperature (meaning if the temperature doubles, the radiation increases by 16 times).
Step 5: Conclude that as the temperature of an object increases, the rate at which it radiates heat also increases significantly.
