Question

What most likely happens when a liquid gains heat?

It changes into gas.
It changes into a solid.
Its temperature decreases.
Its temperature remains constant.

Answer 1

Am I right with A?

Answer 2

Yes

Answer 3

When a liquid gains heat, its molecules loosen up more/move around more. So yes, it would become gas, which has less molecular bonding than liquid.

Answer 4

Although if "its temperature increases" was an option, that would be more correct

Answer 5

Okay, thank you

Answer 6

No problem

Answer 7

The others are wrong because:
B - Solid changing involves DECREASE of energy.
C - temperature decreases? No, the exact opposite.
D - Temperature can't remain constant if more energy is introduced!

Answer 8

I see, thank you
