Occurs when an energy source transfers heat directly to another object through space; an example would be an object becoming warm by sitting in the sunshine. a. conduction c. convection b. radiation d. heat select the best answer from the choices provided a b c d

b. radiation

Explanation:

In order to answer correctly, let's describe the three method of transfer of heat:

1) Conduction: conduction occurs when heat is transferred through two materials which are directly in contact with each other. The transfer of heat occurs because the kinetic energy of the particles in the first medium is transferred through collisions to the particles in the second medium. Conduction can occurs in solids, liquids and gases, but it cannot occur in empty space

2) Convection: convection occurs when a fluid is heated by an external source. In this case, the particles of the fluid closer to the source of heat are heated faster, therefore the area of fluid near the source becomes warmer and less dense, therefore rises and it is replaced by the colder parts of the fluid, and so on, creating a convection current. Convection occurs only in fluids (liquids or gases)

3) Radiation: radiation occurs when a source emits electromagnetic radiation, which carries energy through space and materials. Therefore, radiation can also occur in empty space.

Therefore, the example described:

an energy source transfers heat directly to another object through space; an example would be an object becoming warm by sitting in the sunshine.

Is an example of heat transferred through radiation.

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask
