Exploring States of Matter

What are the three main states of matter?

• plasma, vapor, foam

• solid, liquid, plasma

• gas, liquid, crystal

• solid, liquid, gas

How do the particles in a solid behave?

• Particles in a solid flow like a liquid and change shape easily.

• Particles in a solid vibrate in fixed positions and are closely packed together.

• Particles in a solid are in constant motion and can change positions easily.

• Particles in a solid move freely and are widely spaced apart.

What is the defining characteristic of a liquid?

• Definite volume and shape that changes with temperature.

• No definite shape and no definite volume.

• Definite shape but no definite volume.

• Definite volume but no definite shape.

In which state of matter do particles move freely?

• Plasma

• Liquid

• Gas

• Solid

What happens to the shape of a solid when it is heated?

• The shape of a solid remains unchanged when heated.

• The shape of a solid typically expands when it is heated.

• The shape of a solid contracts when it is heated.

• The shape of a solid melts into a liquid when heated.

How does the density of a gas compare to that of a liquid?

• The density of a gas is higher than that of a liquid.

• The density of a gas varies greatly but is often similar to that of a liquid.

• The density of a gas is equal to that of a liquid.

• The density of a gas is significantly lower than that of a liquid.

What is an example of a gas?

• Oxygen

• Carbon Dioxide

• Hydrogen

• Water

What state of matter has a definite volume but no definite shape?

• solid

• gas

• liquid

• plasma

How do temperature changes affect the state of matter?

• Temperature changes can cause matter to transition between solid, liquid, and gas states.

• Temperature changes only affect gases.

• Temperature changes only affect the color of matter.

• Matter cannot change states regardless of temperature.

What is the process called when a solid turns into a liquid?

• Freezing

• Melting

• Condensation

• Sublimation
