Bob is hanging a pot of water over his campfire to boil water for instant ramen. Which method(s) of heat transfer produce the hot water? Question 5 options:

A. radiation

B. conduction

C. radiation & conduction & convection

D. radiation & convection

E. radiation & conduction

F. convection

The answer would be ( F.)

Convection is the main method of heat transfer in fluids such as water and air.

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.

another example of kinetic energy would be,

kinetic energy   >     moving energy
