5.3 - States of Matter and Matter Changing States (BrainPops)

What are the three main states of matter?

• Solid, liquid, and gas

• Ice, water, and steam

• Temperature, pressure, and energy

• Hot, cold, and warm

What is the definition of matter?

• Matter is anything that is visible

• Matter is anything that has mass and takes up space.

• Matter is anything that reflects light.

• Matter is anything that absorbs light.

What do water vapor, liquid water, and ice have in common?

• The same crystal lattice structure

• The same amount of energy

• The same physical properties

•  The same chemical properties/identity

What's the easiest way to add energy to matter?

• Heating it

• Cooling it

• Decreasing pressure

• Decreasing temperature

What is it called when a solid turns directly into a gas?

• Sublimation

• Vaporization

• Melting

• Fusion

The melting point of water is 0 degrees Celsius. This is the same as its:

• Boiling point

• Vaporization point

• Fusion point

• Freezing point

How do the molecules of a gas behave?

• They vibrate in place.

• They bounce around randomly, quickly, and far apart.

• They are locked in a crystal lattice.

• They clump together.

In what way are liquids different from solids?

• Liquid molecules are lighter than solid molecules.

• Liquids are made of atoms; solids are made of molecules.

• Liquids don't have a fixed shape; solids do.

• Liquids are always denser than solids.

What will happen if you keep increasing the temperature of a liquid?

• It will boil and become a gas.

• It will transpire.

• It will remain a liquid.

• It will solidify.

What happens to the chemical structure of water when it changes state?

• Water molecules break apart to form individual atoms.

• Water molecules harden into ice molecules.

• Water molecules melt into gas molecules.

• Nothing happens to the chemical structure.
