effect of temprature on matter
Creatas/Creatas/Getty Images. 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.he point at which matter subjected to a particular temperature under conditions of constant pressure begins to change its phase is called the phase change threshold. At this temperature, every bit of the substance exposed to the heat will change its state.
