The most tightly bound nucleus with a small number of constituents is 4 he, a bound state of two protons and two neutrons. the mass of 4 he is about 3731.4 mev c 2 , the proton mass is 938.2 mev c 2 and the neutron mass is 939.5 mev c 2 . what is the binding energy of the nucleus?

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.

their crystal patterns have been disrupted by stress
