What substances undergo physical change?
All substances have physical changes.
What is always a characteristic of a chemical change but not always a characteristic of a physical change?
When a chemical change takes place, the chemical structure of particles involved changes (i.e. one or more new substances are formed). In a physical change, the physical state of the particles involved changes (e.g. a solid melts and becomes a liquid). The chemical structure of the particles does not change, and no new substance is formed.
What undergoes physical change?
All substances have physical changes.
What kind of changes in substances are always physical changes?
The kinds of changes in substances that are always physical changes are changes in the state. This is the change from solid, to liquid and then to gas and the reverse.
What are two kind of changes in matter?
Two types of changes in matter are physical changes and chemical changes. Physical changes involve a change in appearance, such as a change in shape or state, without forming new substances. Chemical changes involve a rearrangement of atoms to form new substances with different chemical properties.
What Is the between physical changes and chemical change?
Physical changes is change in property. Ex) change from solid to liquid....ice to water. Chemical change changes to different substances. Ex) rotting of fruit.
Are state changes physical or chemical changes?
State changes are physical changes because they involve a change in the physical properties of a substance, such as its form or state of matter (solid, liquid, gas). No new substances are formed during a state change, making it a physical change rather than a chemical change.
Does physical change differ from a chemical in that waste products are formed through chemical changes?
Yes, physical changes involve a change in the appearance or form of a substance without forming new substances. Chemical changes, on the other hand, involve the formation of new substances through the rearrangement of atoms. Waste products may be formed in chemical changes as new substances are produced.
What does change of state operation?

Is warming chocolate a physical change or chemical change?
