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
