Question

explain "Effect of variable on state of matter"​

Answer 1

Answer:

Explanation:

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.

States of Matter

At low temperatures, molecular motion decreases and substances have less internal energy. Atoms will settle into low energy states relative to one another and move very little, which is characteristic of solid matter. As temperatures increase, additional heat energy is applied to the constituent parts of a solid, which causes additional molecular motion. Molecules begin to push against one another and the overall volume of a substance increases. At this point, the matter has entered the liquid state. A gaseous state exists when molecules have absorbed so much heat energy due to increased temperatures that they are free to move around one another at high speeds
