Freezing and melting are related. Freezing is going from a liquid to a solid, and melting is going from a solid to a liquid. The energy used for this phase change is called heat of fusion. Condensing and vaporizing are also related in a similar way. Condensing is going from a gas to a liquid and vaporization is going from a liquid to a gas. The energy used for this phase change is called heat of vaporization. Evaporation and boiling are similar. Both refer to the change of a liquid to a gas, but evaporation takes place on the surface of the liquid, and boiling takes place on the entire mass of the liquid.
It is a physical change, the substance stay the same elements before and after the change, this is the same for all states of matter changes (melting, freezing, evaporating, condensing, and sublamation)
Water boiling to become steam is an example of a liquid to gas phase change.
the melting point Melting is the opposite of freezing. Condensation is the opposite of boiling.
(Explanation): If it is between the liquid and gas phases, we know that it is at the boiling point of water (liquid boils into gas). So, another way to say boiling is evaporating, and the opposite is condensation, because both are happening at melting point, like they talked about in the lesson.
gas -> liquid = condensing liquid -> gas = evaporating liquid -> solid = freezing solid -> liquid = melting solid -> gas= sublimating liquid -> gas= boiling
Freezing (melting, boiling, condensing) are always phycal changes (of matter)
Melting, freezing, boiling, evaporating, and condensing can be reversible changes as they involve physical processes that involve changes in state of matter. However, other factors such as impurities, pressure, and temperature can also influence whether the changes are reversible or irreversible.

Yes, changes of state (melting, boiling, freezing, condensing) are physical processes.
Water boiling to become steam is an example of a liquid to gas phase change.
There are three main states that a substance can exist as: solid, liquid and gas. The transition between these states occur when a substance is heated or cooled past their freezing/melting or boiling/condensing points. Solid -> Liquid = Melting Liquid -> Gas = Boiling Gas -> Liquid = Condensing Liquid -> Solid = Freezing
the melting point Melting is the opposite of freezing. Condensation is the opposite of boiling.
Everyday physical reactions could include sweating when it's hot, shivering when it's cold, blinking to protect the eyes, and feeling hungry when blood sugar drops. These are automatic responses that help regulate body temperature, protect the body, and signal the need for nourishment.
