States of Matter

• It is a liquid because the volume is fixed, and the shape changes.

• It is a liquid because the substance retains its mass and volume.

• It is a solid because the substance retains its mass and volume.

• It is a solid because the length of the substance cannot be measured, and the shape changes.

• Figure 1; the particles are tightly packed.

• Figure 2; the particles are tightly packed.

• Figure 1; the particles are filling the entire container.

• Figure 2; the particles are far apart.

• The substance is a liquid because the volume of the substance is retained.

• The substance is a solid because the shape of the substance is retained.

• The substance is a solid because the mass of the substance does not change.

• The substance is a gas because the volume of the substance does not change.

• Substance 1 should be classified as a solid, and Substance 3 should be classified as a liquid because a solid does not have a fixed shape.

• Substance 1 should be classified as a solid, and Substance 2 should be classified as a liquid because the volume of a liquid does not change.

• Substance 2 should be classified as a gas, and Substance 3 should be classified as a solid because the particles of a solid have small spaces between them.

• Substance 1 should be classified as a gas, and Substance 3 should be classified as a liquid because the volume of a liquid is fixed.

• The substance is a liquid because it is clear, and its particles are spaced far apart.

• The substance is a liquid because its shape and volume are indefinite.

• The substance is a gas because its shape and volume are indefinite.

• The substance is a gas because it is clear, and its particles are spaced far apart.
