Ways of thinking, feeling, or acting that are unusual are of a mental disorder. a. always a part b. unusual aspects c. functions d. symptoms

Ways of thinking, feeling, or acting that are unusual are symptoms of a mental disorder.

Option (D) is the correct answer.

Explanation:

When a person thinks, feels or acts in ways which are not normal or which are unusual in many ways then this activity is considered as symptoms of a person's behavior.

For example, a women argues with everyone without any reason.

So, when a person suffers from some any mental disorder then he doesn't know what he is saying, doing or expressing.

Hence, we can conclude that ways of thinking, feeling, or acting that are unusual are symptoms of a mental disorder.

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.

i would say the answer is food.

hope this !
