Answer:
As the temperature of a thermal radiator is increased
Group of answer choices
- the object appears redder.
- the object appears bluer.
- the object emits more power for the same area.
- the object emits less power for the same area.
- the object expands to keep the same power per units area.
<em>When the temperature of a thermal radiator increases ;</em>
- <em>the object emits more power for the same are</em>
- <em>the object becomes bluer</em>
Explanation:
Thermal radiation involves the transfer of heat between molecules of two substances without direct contact with each other. When a body is heated to a given temperature it begins to emit light which is transferred to nearby objects as thermal radiation. The medium through which the heat is transferred could be liquid, solid, or in a vacuum.
<h3>How temperature affects thermal radiation.</h3>
Temperature determines the amount of heat that is been radiated from a body. An increase in temperature would increase the thermal radiation of the body. The increase in the heat radiation results to increase in the thermal energy of the body. Also when a body is heated it tends to be bluer than a cool object, this is caused by the rapid movement of the molecules.
Therefore When the temperature of a thermal radiator increases ;
- the object emits more power for the same are
- the object becomes bluer
