Matter
Is love an example of matter?
NO. Love is a feeling/emotion and doesn't take up space and can't be measured.
Name the three states of matter.
Name 2 examples of a solid.
Answers vary.
A puddle drying out is an example of which change in state?
Evaporation (Vaporization)
Explain an example of freezing.
Answers vary.
Is Gabo an example of matter?
YES. Gabo is a physical object that occupies space and has mass.
Name 2 examples of a liquid.
Answers vary.
Name 2 examples of a gas.

When does matter changes states?
Matter can change its state when it experiences a change in temperature and/or pressure.
Explain Melting.
Melting occurs when a solid is heated until its particles reach a high enough energy to reach its melting point, changing it into the liquid state.
Is time an example of matter?
NO. Time can be measured, but it has no mass and occupies no volume.
Do solids have a definite shape?
YES. Solids have a definite shape.
Do solids have a definite volume?
YES. It has a definite volume because it can be measured.
Explain Freezing.
Freezing occurs when a liquid is cooled until its particles reach a low enough energy to reach its freezing point, changing it into the solid state.
Explain Sublimation.
Sublimation is the transition from a solid to a gas without passing through a liquid phase. It occurs when the particles of a solid absorb enough energy to completely overcome the force of attraction between them.
Is air an example of matter?
YES. Air is an example of a gas.
Does liquid have a definite shape?
NO. Liquid does not have a definite shape.
Does liquid have a definite volume?
YES. It does have a definite volume because it can be measured.
Explain Deposition.
This is the process in which a gas changes directly to a solid without going through the liquid state. It occurs when gas particles become very cold.
Explain Evaporation.
It is the process from a liquid to a gas. Evaporation, a type of vaporization, occurs when particles of a liquid reach a high enough energy to leave the surface of the liquid and change into the gas state.
What is matter?
Matter is anything that has mass and takes up space (it has volume and weight).
Does gas have a definite shape?
NO. Gas does not have a definite shape. It sometimes takes the shape of its container and sometimes flies freely around you.
Does gas have a definite volume?
NO. The particles are not connected to each other and takes up whatever space is available.
Explain Boiling.
It is the process from a liquid to a gas. Boiling is a rapid vaporization that occurs when the particles of a liquid are heated to its boiling point. Large bubbles of gas form throughout the liquid and move to the surface, leaving the liquid.
Explain Condensation.
It is the process of a gas to a liquid. Condensation occurs when the particles in a gas cool enough (lose energy) to change to the liquid state.
