Making ice cream and then letting some of it melt are two examples of phase change.
The freezing cold of the ice cream maker causes the liquid cream to give up its heat and turn solid. This freezing phase change is exothermic because energy (heat) comes out of the cream.
If you leave a bowl of ice cream on the table in a warm room, the heat energy of the air will enter into the ice cream and it will become liquid. This melting phase change isendothermic.
Memory tip:
exo - the heat energy exits the cream, which gets colder.
endo - the heat energy goes into the ice cream, which gets warmer.

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 a phase change an example of a physical or chemical or nuclear or a covalent change?
A phase change is an example of a physical change, not a chemical, nuclear, or covalent change. During a phase change, the substance undergoes a change in state (solid, liquid, gas) without any change in its chemical composition.
Is condensation an example of a phase change?
Yes, condensation is an example of a phase change. It is the process in which a gas changes to a liquid as heat is removed.
Which of the following is an example of a phase change from liquid to solid?
Freezing of water is an example of a phase change from liquid to solid.
What is a phase change example of?
When 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.
What is an example of liquid to gas phase change equilibrium?
Water boiling to become steam is an example of a liquid to gas phase change.
The change from a liquid to a gas or solid to a liquid is an example of a change of?
Phase change
How does the physical property of water change?
For example after phase changes.
What is edible in physical change?
In a physical change, the chemical composition of a substance does not change. Edible items that undergo physical changes when cooked include eggs, which change from liquid to solid, and butter, which melts from a solid to a liquid form.
Heating water so that it boils is an example of .?
Vaporization is a change of phase.
What is an example of the liquid-gas phase-change equilibrium?
Evaporating and condensing.
What is an example of the liquid-to-gas phase change Equilibrium?
Evaporating and condensing.
