Question

read and answer the questions to assess your prior knowledge of the content.

1. which state of matter has a definite shape and volume?

a. gas
b. liquid
c. solid
d. plasma

1. liquids and gases-

a. have the same density.
b. take the shapes of their containers.
c. both have definite shapes.
d. are denser than solids.

1. matter can be divided into tiny particles called-

a. liquids, which are made of large particles.
b. compounds, which are denser than water.
c. solids, which have a fixed mass.
d. atoms, which are too small to be seen and have energy.

1. the energy of molecules in liquids-

a. is greater than the energy of atoms in solids but less than the energy in gases.
b. is the same as the energy of atoms in solids and gases.
c. decreases as temperature rises.
d. disappears when the liquid turns to a solid.

1. which of the following is not true about the structure of matter in solids and liquids?

Explanation:

1. Solids have a definite shape and volume due to closely - packed particles.
2. Liquids and gases take the shape of their containers as particles are more free - moving compared to solids.
3. Matter is made up of tiny atoms which are too small to be seen and have energy.
4. Molecules in liquids have more energy than in solids but less than in gases as the particle movement and spacing vary.
