Examine the scenario. an object is placed in a magnetic field where its magnetic domains are aligned. it is then removed from the magnetic field and heated. its magnetic domains are now random. which choice correctly describes the object?

the object is a temporary magnet because its domains become random when heated and removed from the field. temporary magnets require both of these actions to happen in order to randomize its domains.

the object could be a temporary or permanent magnet. the domains in temporary magnets become random if taken out of the field. the domains in permanent magnets can become random if heated.

the object is neither a permanent or temporary magnet because it could not maintain the alignment of its magnetic domains.

the object is a permanent magnet because its domains became random when heated and removed from the field. permanent magnets have random domains if either of these actions happen.

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.
