Where do the changes of state occur?
Changes of state occur at the molecular level when substances transition between solid, liquid, and gas phases. These changes typically happen when energy, usually in the form of heat, is added or removed from a substance, causing its molecules to either gain energy and move apart or lose energy and come closer together. Common examples include melting (solid to liquid), freezing (liquid to solid), evaporation (liquid to gas), and condensation (gas to liquid). These processes occur at specific temperatures and pressures characteristic of each substance.
Where do changes of state occur?
Changes of state occur at the boundaries between different phases of matter, such as solid, liquid, and gas. These transitions happen when energy is added or removed, leading to transformations like melting (solid to liquid), freezing (liquid to solid), evaporation (liquid to gas), and condensation (gas to liquid). Changes of state typically occur at specific temperatures and pressures, known as phase transition points, such as the melting point and boiling point.
Which of the physical changes release heat?
Exothermic reactions release heat as they occur, such as combustion, oxidation, and some neutralization reactions. Other physical changes that release heat include processes like freezing, condensation, and deposition.
What is process of gas to solid?
Gas to solid is a process known as deposition where gas molecules lose energy and come together to form a solid on a surface. This can occur through physical processes such as condensation, where the gas cools and changes state directly to a solid, or through chemical processes where the gas molecules react to form a solid product.
When a substance changes from a liquid to a gas energy is . When a substance changes from a gas to a liquid energy is .?
When a substance changes from a liquid to a gas energy is absorbed. When a substance changes from a gas to a liquid energy is released.
How does water changes to solid liquid and gas?
Water changes from a solid to a liquid through melting and from a liquid to a gas through evaporation. The reverse processes are freezing (liquid to solid) and condensation (gas to liquid). These changes in state occur due to variations in temperature and pressure.
When does phase changes occur?
When a solid melts or changes to a liquid. When a liquid boils or changes to a gas. or the reverse when a gas condenses to a liquid or a liquid freezes to a solid. Also it is possible for a solid to go directly to a gas without passing through the liquid stage. This is called sublimation and can occur with sulfur when heated, or ice in the winter when the sun shines on it..
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 process changes a liquid to a gas or vapor?
These processes are evaporation and boiling.
Is condensation and evaporation reversible?
Yes, condensation and evaporation are reversible processes. Condensation is the transition of a substance from gas to liquid, while evaporation is the transition from liquid to gas. Both processes can occur depending on changes in temperature and pressure.
What is the process from a liquid to gas and gas to liquid?
The process from a liquid to a gas is called evaporation, where the liquid absorbs heat energy and changes into a gas. On the other hand, the process from a gas to a liquid is called condensation, where the gas loses heat energy and changes into a liquid. Both processes involve a change in temperature or pressure.
What is evaporation condensation and precipitation?
The processes that occur in the water cycle: precipitation: when liquid or solid water falls from clouds transpiration: water evaporating out of plants condensation: when water vapor changes into liquid evaporation: when liquid becomes gas

When a plasma changes into gas what is called?
Ironisation is the process of changing gas into plasma. Other processes of changing state include: Solid -> liquid = melting Liquid -> gas = condensation Gas -> liquid = evaporation Liquid -> solid = freezing Solid <- -> Gas = sublimation
