Question
A change in which the characteristics of a substance are only changed physically and the chemical composition stays the same
- Chemical change
- Chemical equation
- Chemical reaction
- Physical change
Hint:
There are two types of change one in which there is a change in only physical appearance only and the other one is chemical change in which there is a change in chemical composition only.
The correct answer is: Physical change
A change in which the characteristics of a substance are only changed physically and the chemical composition stays the same is Physical change.
- Physical alterations or changes are those in which a substance experiences a change in its physical characteristics.
- (1) Physical changes don't produce any new substances.
- (2) A transitory change is one that affects the body.
- (3) A physical modification is simple to undo.
- (4) A physical change either absorbs or evolves very little energy.
