Question

Two samples of carbon come into contact. Heat will transfer from Sample A to Sample B if the average kinetic energy of Sample A's atoms is _______ the average kinetic energy of Sample B's atoms.

Answer 1

Explanation:

When two substances of different temperature are in contact with each other then heat will flow from hot object to cold object until a thermal equilibrium is maintained between them.

Kinetic energy is the energy obtained due to the motion of an object is known as kinetic energy. Total kinetic energy of all the particles present in a system is known as average kinetic energy.

Thus, we can conclude that when two samples of carbon come into contact. Heat will transfer from Sample A to Sample B if the average kinetic energy of Sample A's atoms is greater than the average kinetic energy of Sample B's atoms.

Answer 2

Answer:

The right word to fill the blank space is GREATER THAN.

Explanation:

In nature, heat in form of temperature is usually transfer from the region of higher temperature to the region of lower temperature. Thus, for heat to be transfer from one substance to another one, the temperature will flow from the body with the higher temperature to that which has a lower temperature, the substance that is giving out the heat must have a higher temperature.
