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
