What state of matter has the weakest intermolecular forces?

• solid

• liquid

• gas

What state of matter has the strongest intermolecular forces?

• solid

• liquid

• gas

Why does liquid water take the shape of the container, but solid ice does not?

• because the molecules in water are softer than the molecules in ice

• because the molecules in water are smaller than the molecules in ice

• because the molecules in water are moving the molecules in ice are not moving

• because the molecules in water slide past each other and the molecules in ice do not

Dry ice changing from solid to gas is called

• diffusing

• melting

• condensation

• sublimation

Water vapor changing directly into a solid is called

• condensation

• evaporation

• sublimation

• deposition
