Term
 Q: What is condensation?
Definition
 A: Condensation is the change of state of a substance from a gas into a  liquid. Dew on grass is an example of this change of state. [image]
Term
 Q: What is solidification?
Definition
 A: Solidification is the change of state of a substance from a liquid into a solid. An example of solidification is water turning into ice. [image]
Term
 Q: What is sublimation?
Definition
 A: Sublimation is the change of state of a substance directly from a solid into a gas. An example of sublimation is dry ice [image]
Term
 Q: What is evaporation?
Definition
 A: Evaporation is the change of state of a substance from a liquid into a gas. The boiling point is the temperature in which a this change of state happens. An example of evaporation is steam from a tea kettle  [image]
Term
 Q: What is a fluid?
Definition
 A: A fluid is anything that can flow. Liquids and gases are fluids, but a solid is not because it has a fixed shape.[image]
Term
 Q: What is mass?
Definition
 A: Mass is the amount of matter something contains so the more matter, the greater the mass, the mass is often measured in grams or kilograms. If you know the density and volume of an object or substance, you can multiply them and obtain the mass.
Term
 Q: What is volume?
Definition
 A: Volume is the the space that a substance or object takes up. Volume is either measured in millilitres (liquids) or cubic centimetres (solids). If you know the mass and density of the object or substance, you can find it by dividing mass by density.
Term
 Q: What is density?
Definition
 A: Density is the mass of a given volume, usually measured in g/cm3 or g/mL. If you know the mass and volume of an object or substance, you can divide the mass by volume and get the density.
Term
 Q: What is melting?
Definition
 A: Melting is the change of state of a substance from a solid into a liquid. The melting point is the temperature in which this change of state occurs. For example, ice can melt into water. [image]
Term
 Q: What is displacement?
Definition
 A: Displacement is the amount of space that is taken up by an object within a fluid. You can use this method to find the volume of an irregularly-shaped object. [image]
