∙ 12y ago1. Solid to liquid - melting (ice to water)
2. Liquid to gas - vaporization (water to water vapor)
3. Liquid to solid- crystallization (freezing - water to ice)
4. Gas to liquid - condensation (making liquid nitrogen)
5. Gas to plasma - ionization
More rarely observed is :
6. Solid to gas (sublimation - dry ice to carbon dioxide)

∙ 13y agoThis phase change is called sublimation. Although rare at standard temperature and pressure it can be seen.
The most common example is "dry ice", which is solidified Carbon Dioxide.
Naphthalene, commonly known as mothballs, also sublimates but is much less dramatic.

∙ 15y agoWhen ice melts and becomes water, that is a phase change. Same when water boils and becomes steam (a gas) that is also a phase change.

Are phase changes physical or chemical in nature?
A phase change is a physical change. It is not a chemical change.
What do the lines on a phase diagram represent?
The lines show where a phase changes happens to a substance -
What phase changes require the subtraction of heat energy?
Phase changes requiring the addition of heat energy are the phase changes from solid to liquid, liquid to gas, and solid to gas. These phase changes are termed melting (solid to liquid), evaporation (liquid to gas), and sublimation (solid to gas).
What are the phase changes processes taking place when a substance is in equilibrium between liquid and gas phase?
Evaporating and condensing
Which of these phase changes does NOT involve changing a liquid to gas?
Sublimation
Phase changes are examples of what changes?
Puberty
Melting is an example of a?
Melting is an example of a phase change. The substance is going from the solid state to the liquid state.
Is wood a sublimatory substance?
No. A sublimatory substance changes from the solid phase directly to the gas phase without passing through a liquid phase. Two examples are dry ice (solid CO2) and iodine.
Why phase changes are reversible'?
Phase changes are accompanied with optical contrast and therefore the feasibility of phase.
Differences between physical and chemical changes?
A physical change is a change that does not change the chemical makeup of the substance. This can be crushing, tearing, or a phase change for example. A chemical change changes the chemical makeup of the substance. Some examples of this are rusting, combustion, or digestion.
What are phase changes?
its physical changes
What are some examples of heat energy changes?
bulb
What are the phase changes of matter?
The melting phase changes are Solid~Liquid~Gas and the freezing phase changes are Gas~Liquid~Solid
What are some physical examples?
physical examples are examples of thing or changes or transformations which you can see with you eyes or hold with your hands.
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.
What are changes in phase physical changes?
Because it changes its form.
What are some examples of useful changes in your environment?
