Which object has the most thermal energy?

B

Explanation:

The object with the most thermal energy is the choice B. This is because from the given choices, it has the most mass and highest temperature of all the bricks.

Thermal energy is the sum total of the average kinetic energy within the system.

It is mathematically expressed as:

    Quantity of energy  = mass   x  specific heat x  change in temperature

We see that the quantity of the thermal energy is directly proportional to mass and temperature changes.

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
