This process separates mixtures of pure substances by boiling. The evaporated substance is collected and cooled back into a liquid.
What is distillation.
_________ is the amount of matter in an object. It can be measured in gram or kilograms.
What is mass.
_____________ occur when substances are cooled or heated.
What are changes of states.
This type of energy is involved in the transfer of heat between objects.
What is thermal energy.
In which direction does light travel?
What is a straight line.
This process is used to separate small, solid particles that are suspended in water.
What is filtration
________ is the amount of space an object occupies. Solids are usually measured in cubic centimeters while liquid is measured in milliliters or liters.
What is volume.
_________ are changes in the shape of materials when a force is exerted on them.
What are deformations.
This type of energy is stored in matter. Objects that burn contain this energy. We store this energy in our bodies.
What is chemical energy
This type of material does not allow light to travel through it.
What is opaque material
This process separates mixtures of solid and liquid solutions by boiling them.
What is evaporation.
________ is the relationship between the mass and volume of an object. It is usually measures in g/cm or kg/m.
what is density.
This process occurs when something like wood, combines with oxygen and a spark and burns.
What is combustion.
