What happens to the particles in a gas?

• The particles are tightly packed and vibrate in place.

Name a property of a gas?

• Gases expand to fill their container.
• Gases have a definite shape.
• Gases cannot be compressed.
• Gases have a fixed volume.

Describe the behaviour of particles in a solid.

• Particles in a solid vibrate in fixed positions and are closely packed, giving solids a definite shape and volume.
• Particles in a solid have high kinetic energy and can easily change shape.
• Particles in a solid are widely spaced and can flow like liquids.
• Particles in a solid move freely and are not fixed in place.

Describe the behaviour of particles in a liquid?

• Particles in a liquid are closely packed, can move freely past each other, and have a definite volume but no fixed shape.
• Particles in a liquid are in a solid state and cannot flow.
• Particles in a liquid have a fixed shape and volume.
• Particles in a liquid are widely spaced and do not move.

What does viscosity mean?

• Viscosity is the temperature at which a fluid boils.
• Viscosity refers to the density of a fluid.
• Viscosity is the measure of a fluid's color.
• Viscosity is the measure of a fluid's resistance to flow.

Why do liquids have different viscosities?

• Liquids have different viscosities due to variations in molecular size, shape, and intermolecular forces.
• All liquids have the same molecular structure, leading to uniform viscosity.
• Viscosity is solely determined by the temperature of the liquid.
• Liquids have the same viscosity regardless of their composition.

What is another word for a particle?

• molecule
• cell
• compound
• atom
