temperature
nature of surroundings
Factors such as the amount of a substance, its chemical composition, and the presence of impurities will not change its state of matter. For instance, heating or cooling a substance can change its state (e.g., solid to liquid), but simply having more or less of the same substance at the same temperature and pressure will not alter its state. Additionally, the state of matter remains unchanged as long as the temperature and pressure conditions stay constant.
The two factors that determine the state of a substance are temperature and pressure. These factors influence whether a substance exists as a solid, liquid, or gas.
Factors affecting the state of a substance include temperature, pressure, and the intermolecular forces between the particles of the substance. Changes in these factors can lead to a substance transitioning between solid, liquid, and gas states.
change of state
A substance changes from one state of matter to another by either gaining or losing energy. For example, to change from a solid to a liquid, energy is added to break the intermolecular bonds. To change from a liquid to a gas, more energy is added to overcome the forces of attraction between the molecules.
change is complete
False. The temperature of a substance remains constant during a change in state until all of the substance has completed the phase change.
This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.
One possibility is a change in state.
change of state
physical change
After a physical change a substance does not change its chemical composition it simply changes its state as, water to ice or vapours.
