What happens to a solid when heat is added?
It remains unchanged.
It melts and becomes a liquid.
It turns into gas immediately.
It becomes a solid again.
What is plasma?
A state of matter where gas is energized until atomic particles are freed.
A liquid state of matter that has a fixed volume but no fixed shape.
A solid state of matter that maintains a fixed shape and volume.
A gaseous state of matter that is completely ionized and conducts electricity.
What happens to the particles of a gas when it condenses?
The particles gain energy and spread apart, becoming a gas.
The particles lose energy and come closer together, becoming a liquid.
The particles remain unchanged and stay as a gas.
The particles increase in temperature and become a solid.
What is the freezing point of water?
-10 degrees Celsius (14 degrees Fahrenheit)
0 degrees Celsius (32 degrees Fahrenheit)
100 degrees Celsius (212 degrees Fahrenheit)
-5 degrees Celsius (23 degrees Fahrenheit)
What is an example of sublimation?

Water boiling into steam.
Ice melting into water.
Sugar dissolving in water.
What is the process of changing from solid to gas called?

What is a gas?
A state of matter that has no defined shape or volume and expands to fill its container.
A liquid that has a fixed volume but no fixed shape.
A solid that maintains its shape and volume regardless of the container.
A form of matter that can only exist at extremely high temperatures.
What happens to a liquid when heat is added?
It freezes and turns into solid.
It evaporates and turns into gas.
It remains unchanged.
It becomes denser and sinks.
What happens to the particles of a gas when it cools down?
The particles gain energy and move further apart.
The particles lose energy and come closer together, eventually turning into a liquid.
The particles remain unchanged and stay in the same position.
The particles increase in speed and become a solid.
What happens to the particles in a solid when it melts?
The particles lose energy and become more tightly packed.
The particles gain energy and move more freely, becoming a liquid.
The particles remain stationary and unchanged.
The particles break apart into individual atoms.

What is the main difference between solids, liquids, and gases?
Solids have very close particles that vibrate, liquids have loose particles that can flow, and gases have very separated particles that move freely.
Solids are always in a fixed shape, liquids take the shape of their container, and gases have a definite volume.
Solids can flow, liquids cannot, and gases have a fixed shape.
Solids are made of large particles, liquids are made of small particles, and gases are made of tiny particles.
What is an example of a substance that can exist in all three states of matter?
Water
Oxygen
Iron
Carbon Dioxide
What is an example of condensation?
The formation of water droplets on the outside of a cold glass.
The evaporation of water from a puddle on a sunny day.
The melting of ice into water.
The freezing of water into ice cubes.
