During a phase change, the arrangement of the particles changes while the chemical composition remains the same. Energy is absorbed or released, causing changes in temperature and state. Phase changes include processes like melting, freezing, vaporization, condensation, and sublimation.
When a substance changes from one physical form to another, you say the substance has had a phase change or undergone a phase transition.
Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid. Vaporization: the substance changes from a liquid to a gas. Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.
Phase changes are physical changes in nature. They involve a change in the state of matter (solid, liquid, gas) rather than a change in the chemical composition of the substance. Heating or cooling a substance can trigger phase changes.
A phase change does not affect the mass of a substance because mass is a constant property of matter. During a phase change, such as melting or boiling, the substance's molecular arrangement changes, but the total mass remains the same.
The phase change in which a substance changes from a gas to a liquid is called condensation. It occurs when the temperature of the gas decreases to reach its condensation point, causing the gas molecules to come together and form a liquid.
When a substance changes from one physical form to another, you say the substance has had a phase change or undergone a phase transition.
The phase change in which a substance changes from a gas to a liquid is called condensation. This occurs when the gas loses energy, typically through cooling, and transitions to a liquid state.
Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid. Vaporization: the substance changes from a liquid to a gas. Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.
this phase change is called condensation
During phase changes the temperature of a substance does not change.
Phase changes are physical changes in nature. They involve a change in the state of matter (solid, liquid, gas) rather than a change in the chemical composition of the substance. Heating or cooling a substance can trigger phase changes.
Deposition is the phase change in which a substance changes directly from a gas to a solid without passing through the liquid phase. It occurs when the temperature of a gas decreases to such an extent that particles lose energy and come together to form a solid.

It is condensation.
