5th Matter Science Study Guide

Name the three states of matter.

• Solid, liquid, gas

• Solid, liquid, plasma

• Solid, gas, plasma

• Liquid, gas, plasma

What is matter?

• Anything that takes up space

• made of particles called atoms and molecules

Define atoms.

• Atoms: the tiniest bits of matter

• Atoms: large celestial bodies

• Atoms: complex molecules

• Atoms: fictional entities

Define molecules.

• Molecules: when atoms stick together

• Molecules: when electrons are shared between atoms

• Molecules: when atoms are ionized

• Molecules: when atoms are isolated

What is the melting point?

• Melting point: the temperature at which particles move fast enough to melt (from solid to liquid)

• Melting point: the temperature at which particles freeze (from liquid to solid)

• Melting point: the temperature at which particles evaporate (from liquid to gas)

• Melting point: the temperature at which particles condense (from gas to liquid)

What is the boiling point?

• Boiling point: the temperature at which particles move fast enough to boil (liquid to a gas)

• Boiling point: the temperature at which particles move slow enough to freeze (liquid to a solid)

• Boiling point: the temperature at which particles move fast enough to melt (solid to a liquid)

• Boiling point: the temperature at which particles move slow enough to condense (gas to a liquid)

What is evaporation?

• Evaporation: when heat is added to a liquid and causes vaporization

• Evaporation: when a liquid turns into a solid due to cooling

• Evaporation: when a gas turns into a liquid due to cooling

• Evaporation: when a solid turns directly into a gas without becoming liquid

What is condensation?

• Condensation: when a liquid cools, causing precipitation (or liquid droplets)

• Condensation: when a gas turns into a liquid upon cooling

• Condensation: when a solid turns directly into a gas

• Condensation: when a liquid turns into a gas upon heating

What does opaque mean?

• Opaque: CANNOT see through it!

• Opaque: CAN see through it!

• Opaque: Partially transparent!

• Opaque: Reflects light!

What does translucent mean?

• Translucent: some light passes through, but not see-through

• Translucent: completely see-through

• Translucent: no light passes through

• Translucent: reflects all light
