Name one property of a liquid.

Takes the shape of its container / can flow / has a fixed volume

What is the smallest particle that still keeps the properties of an element?

Atom

What is the process called when a liquid changes into a gas?

Evaporation (or vaporisation)

What state of matter is water at room temperature?

Liquid

Explain the difference between a physical change and a chemical change.

A physical change does not create a new substance; a chemical change creates a new substance.

What is a mixture?

Two or more substances physically combined.

What are the three common states of matter?

Solid, liquid, gas

Why are gases easy to compress?

There is lots of empty space between particles.

In which state of matter are particles packed closest together?

Solid

Give one example of a physical change.

Melting ice, dissolving salt, tearing paper, boiling water

What happens to particles during diffusion?

They spread out until evenly distributed.

Which state of matter has no fixed shape or fixed volume?

Gas

What is the process called when a gas changes directly into a liquid?

Condensation

True or False: Particles in a solid do not move at all.

False (they vibrate in place)

What is diffusion?

The movement of particles from an area of high concentration to an area of low concentration.

What happens to particle movement when temperature increases?

Particles move faster.

Name two things that can speed up evaporation.

Higher temperature, larger surface area, wind, lower humidity

A student leaves a puddle of water outside. After a few days it disappears. What process occurred?

Evaporation

Why can you smell perfume from across a room?

Diffusion – particles spread from high concentration to low concentration.

A balloon gets bigger when warmed. Why?

Gas particles move faster and spread out more.

What happens to particles when a solid melts?

They gain energy and move further apart.
