Question

what is the difference between physical change and chemical change.....​

Answer 1

Answer:

Physical Changes are temporary and chemical changes are permanent

Answer 2

• When a substance undergoes a physical change, its composition remains the same despite its molecules being rearranged.
• When a substance undergoes a chemical change, its molecular composition is changed entirely. Thus, chemical changes involve the formation of new substances.

• Physical change is a temporary change.
• A chemical change is a permanent change.

• A Physical change affects only physical properties i.e. shape, size, etc.
• Chemical change both physical and chemical properties of the substance including its composition
