Question

state the type of changes when there is change of statemelting freezing boiling evaporation condensation sublimation

Answer 1

The different types of changes when there is a change of state include melting, freezing, boiling, evaporation, condensation, and sublimation.

Step-by-step explanation:

The changes mentioned in the question refer to the different physical processes through which matter can change state. Here are the types of changes:

1. Melting: The change from a solid to a liquid state, which occurs when a substance absorbs enough heat energy.
2. Freezing: The change from a liquid to a solid state, which occurs when a substance loses enough heat energy.
3. Boiling: The change from a liquid to a gas state, which occurs when a substance is heated to its boiling point and the vapor pressure becomes equal to the atmospheric pressure.
4. Evaporation: The change from a liquid to a gas state at temperatures below the boiling point, which occurs at the surface of a liquid.
5. Condensation: The change from a gas to a liquid state, which occurs when a gas loses enough heat energy.
6. Sublimation: The change from a solid to a gas state without passing through the liquid state, which occurs when the vapor pressure of a substance is higher than its melting point at a given temperature.
