Why are some forces considered to be noncontact forces? if the answer is right i will give u a must be correct.

Contact force happen due to the contact between two different objects. Noncontact force occurs because of either attraction or repulsion between two objects such that there is no contact between these objects.one example of it is Gravitational force is a non-contact force

Explanation:

Lucky ima major in physics

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.
