∙ 12y agoThe change that occurs is that it will look different; although the atoms in the item did not change like a piece of ripped paper. The shape of the full paper has turned into halves, and the atoms were separated. For example, frozen water is a physical change because it looks different. But the atoms did not change, it was just the temperature.

Physical change is a change of the state of matter (melting, freezing, boiling), form (grinding, cutting, etc.), etc. A physical change does not involve the chemical nature of the molecules; the molecules remain unchanged.

What physical changes happens during evaporation?
The transformation of a liquid to a gas.
What is a characteristic that best describes what happens during a physical change?
There are no chemical changes.
When the physical state of a substance changes during a phase what happens to the temperature of the system?
The temperature remain constant during a change of phase.
What happens when you turn solid into liquid into a gass?
These are changes in physical state, which are physical changes.
Which changes occur during evaporation?
Physical changes
What happens to the characteristics of a substance during a physical change?
The change in characteristics is entirely dependent on how you have physically changed it. However most physical changes effect shape and size.
What happens to copper when it turns green?

What happens to mass during chemical and physical changes. explain?
Law of Conservation of Mass: mass can not be created or destroyed, it can only be changed (transformed).
How can you tell if a physical reaction is occuring?
During a physical change the chemical molecule is not affected; physical changes are changes of phase or form.
During an energy change?
What changes and what remains the same during a physical change
Is evaporation of gasoline a example of physical change?
All changes of state are physical changes. Nothing happens to the molecules of gasoline when it evaporates, they just get further apart.
What happens to the energy that is released during an earthquake?
It is dissipated in making physical changes to the rock layers, and to the ground surface, objects, and buildings. Some is released as thermal energy.
