What are the phase changes of matter?
The phase changes of matter are melting (solid to liquid), freezing (liquid to solid), vaporization (liquid to gas), condensation (gas to liquid), sublimation (solid to gas), and deposition (gas to solid). These transitions occur due to changes in temperature and pressure.
What happens when a substance changes state from a solid or liquid?
When a substance changes state from a solid to a liquid, it undergoes melting where it gains enough energy to break the bonds holding its particles together. When it changes from a liquid to a gas, it undergoes vaporization where it gains enough energy to overcome the forces of attraction between its particles.
What does the flat line on cooling curves represent?
The flat line on a cooling curve represents the phase transition of a substance from liquid to solid. During this phase transition, the temperature remains constant as the substance changes from a liquid state to a solid state.
What does a liquid become when you cool it and it changes phase?
When you cool a liquid and it changes phase, it becomes a solid. This process of change of state from liquid to solid is known as freezing or solidification.
Describe four examples of changes in state?
Melting: When ice is exposed to heat, it changes from a solid to a liquid state. Evaporation: When water is heated, it changes from a liquid to a gaseous state. Freezing: When water is cooled, it changes from a liquid to a solid state. Sublimation: When dry ice (solid carbon dioxide) is heated, it changes directly from a solid to a gaseous state without becoming a liquid.
What happens when a solid changes to a liquid?
nothing happens after a solid chages into a liquid.
What happens to water when it changes from a liquid to a solid?
A LIQUID FREEZES TO SOLID
When you saw the changes to a liquid the temperature at which this happens just called?
What's the temperature at which this happens when changes to a solid to a liquid
When a solid changes to a liquid what is the officialname?
According to the textbook "Heating and Cooling Essentials" When a solid changes to a liquid or vice versa, it is simply called "change of state".
What happens at the melting of a substance?
The solid changes into a liquid
When liquid changes to solid here is heat?
When this happens,the liquid loses all its heat & becomes solid.
Condensation happens when a gas changes into an?
Condensation happens when a gas or a vapor changes into a liquid or a solid. H2O (v) ----->H2O (l or s) V= vapor L=liquid S=solid
What happens when water changes from solid to liquid?

What happens to a substance during changes between solid and liquid?
It can melt into a liquid, it can be juiced,
What happens to substance during changes between solid and liquid?
It can melt into a liquid, it can be juiced,
What happens when you turn solid into liquid into a gass?
These are changes in physical state, which are physical changes.
What happens when water changes from a solid to a liquid to a vapor?
When water changes from a solid to a liquid, it undergoes melting. When it changes from a liquid to a vapor, it undergoes evaporation. These changes are driven by increases in temperature and energy levels.
