Question

What is the energy that travels spontaneously from a warm object to a cold object?

1) Conduction
2) Convection
3) Radiation
4) None of the above

Answer 1

The energy that spontaneously moves from a warm object to a cooler one is known as radiation, which is the transfer of energy via electromagnetic waves.OPTION C

Step-by-step explanation:

The energy that travels spontaneously from a warm object to a cold object is described by three mechanisms: conduction, convection, and radiation. Conduction occurs when heat is transferred through physical contact between stationary objects, like when a pan heats up on a stove. Convection involves the movement of heat by the large-scale movement of fluid, such as warm air rising from a fireplace.

Radiation, however, is the transfer of energy through electromagnetic waves, such as the heat we feel from the sun. In the context of the question, the answer is radiation, because it is the only method that does not require matter to facilitate the transfer and can occur through a vacuum or across space.
