3. A ___________has a free surface, whereas a
does not.
4. A solid must be given _____
before it can melt into liquid. This energy is used to over- come ________forces between its particles.
5. During _________a solid gets converted into vapour without melting.​

Answer 1

Answer:

1 . straight line

2. Because of the strong intermolecular force of attraction in solids, the particles are compact and thus solids are rigid and have a definite shape.

3.Liquid contain only one free surface

4. A solid must be given heat before it can melt into liquid. This energy is used to overcome the attraction forces between its particle

5.Sublimation
