Question

Q3 Can a liquid change into gas without heating Give one example​

Answer 1

Answer:

no, it cannot change into gas without heating

example: like a water changed into vapours by heating

Answer 2

Answer:

Not exactly

Explanation:

You can say water turns into hydrogen and oxygen gas during electrolysis

but this is a chemical reaction, so not exactly a physical change.....

But a liquid needing high pressure to conserve it's state, can turn into gas when pressure is reduced ( for example Carbon Dioxide needs 5.1 atm of pressure to exist as liquid)

Hope this helps
