1. how is the temperature of a gaseous substance affected when it is condensing? a. it increases. b. it decreases. c. it stays the same. 2.how is the mass of a gaseous substance affected after it condenses? a. it increases. b. it decreases. c. it stays the same. 3.how is the mass of a liquid substance affected after it boils? a. it increases. b. it decreases. c. it stays the same.

matter can exist in a solid, liquid or gaseous state, and the state a substance is in can be largely determined by its temperature. when a certain temperature threshold unique to each substance in the universe is crossed, a phase change will result, changing the state of the matter. under conditions of constant pressure temperature is the primary determinant of a substance's phase. the differential in temperatures and the phases of different kinds of matter allows for the operation of heat engines and refrigerators.

the real answer is actually (a) hope this

the answer is d (apex) good luck : ))

answer: c.
