no, but the molecules spread out. so it appears the mass has increased, but it hasn't.
The mass remain unchanged.
Neither - heating has no effect on mass.

As a heated liquid turns into a gas, it ... ?
Heating gasses or liquids has no effect on their masses.
they get heated up and evaporate
A heated liquid become a gas at the boiling point.
Heating gasses or liquids has no effect on their masses.
There's no reason for the mass of anything to depend on its temperature.
a liquid turns into gas when it is heated...
When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules. When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules.
First of all, mass is NOT the same as weight. Mass never changes, but weight, however, does change. ================================= To answer the question: If a solid object is heated so as to make it expand, or a sample of liquid is heated and it expands as a result, or a sample of gas is allowed to expand by enlarging the container in which it is confined, neither the mass nor the weight of any of these changes as a result of its increased dimensions.
