When asked to describe resistance you say, "it is an object's ability to

The correct answer to the question is - oppose the flow of current through substances.

EXPLANATION:

From Ohm's law, we know that current [ I ] flowing a wire is directly proportional to the potential difference [ V ] maintained across the two ends of the conductor at constant temperature and pressure.

Mathematically  V ∝ I .

                         ⇒ V = IR .

Here, R is the proportionality constant called resistance of the wire.

From above, we see that current flowing through a wire is inversely proportional to the resistance. It means that the current flow will be less with the increase of resistance of the wire.

Hence, resistance can be defined as the opposition to the flow of current in an electric wire.

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.
