Question

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 obhect expands to keep the same power per units area.

Answer 1

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.

When the temperature of a thermal radiator increases ;

• the object emits more power for the same are
• the object becomes bluer

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.

How temperature affects thermal radiation.

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
