Consider the two points B(2,4) and C(-1,-5) in the xy-plane. The coordinates are given in meters. A 20-N force is applied at point B at 120 degrees counterclockwise from the positive direction of the x-axis (where positive direction is horizontal to the right). Note that the force vector is also in the xy-plane (2D case). What is the magnitude of the moment of this force about point C?

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.
