How do states of matter change?

Question

Natalie Anton · Accepted Answer

By application of energy

Heat causes a solid to become a liquid, which then becomes a gas. The inverse process yields results in the opposite order, i.e., gas->liquid->solid.

Natalie Anton · Answer

Entropy. Each state of matter has a different level of organization or disorder. Moving from one state to another requires or releases energy.

Oddly freezing is an exothermic reaction. When liquid water becomes a solid it becomes more organized and structured This is a decrease in entropy or disorder. As the natural tendency of all the universe is to go from order to disorder. Energy is released and the water becomes colder as it loses energy. Melting ice is an endothermic reaction. When solid water ( ice) is heated energy is added to the system. The energy is absorbed breaking the hydrogen bonds that hold the water molecules together as a solid. The temperature of the water does not increase until all of the solid is melted into a liquid. This is an increase in entropy as the water is less organized and structured than the ice. The transitions from liquid to gas and gas to liquid are much the same. Water is more structured than gas ( steam) . So when a gas condenses into a liquid heat is released. (exothermic) This is why steam can burn if it touches skin. Turning water into steam requires energy ( endothermic)

undefined States of matter change through processes such as melting (solid to liquid), freezing (liquid to solid), evaporation (liquid to gas), condensation (gas to liquid), sublimation (solid to gas), and deposition (gas to solid).

Cooper Anderson · Answer

undefined States of matter change through processes called phase transitions. There are several types of phase transitions:

1. Melting: Solid to liquid.
2. Freezing: Liquid to solid.
3. Vaporization: Liquid to gas.
4. Condensation: Gas to liquid.
5. Sublimation: Solid to gas.
6. Deposition: Gas to solid.

These phase transitions occur due to changes in temperature and pressure. Heating typically increases the energy of particles, causing them to move more freely and transition to a higher energy state. Cooling decreases particle energy, causing them to slow down and transition to a lower energy state. Pressure can also influence phase transitions by affecting the spacing and movement of particles.
