Question

write a note on the effect of a physical as well as chemical change on a substance. Give an example too.​

Answer 1

Answer:

Boiling waterBoiling water is an

example of a physical change and not

a chemical change because the water

vapor still has the same molecular

structure as liquid water (H20). If

the bubbles were caused by the

decomposition of a molecule into a gas

(such as H20-H2 and 02), then boiling

would be a chemical change.
