Properties of Matter
This is a measure of how much matter is in an object.
Mass
A change in matter that does not alter its identity.
Physical Change
The ability to do work or cause change.
Energy
Law stating matter cannot be created or destroyed in a closed system.
law of conservation of matter
The SI unit used to measure mass.
Kilogram
This property depends on both mass and the acceleration due to gravity.
Weight
A change that produces new substances.
Chemical Change
This type of energy is stored due to an object's position.
Potential Energy
Principle that energy can neither be created nor destroyed, only transformed.
law of conservation of energy
Unit for measuring volume of a liquid, often in liters.
Liter
Matter that has a definite shape and volume.
Solid
The process by which a liquid becomes a gas.
Evaporation (or Vaporization)
Type of energy due to motion.
Kinetic Energy
The concept that matter is made up of particles too small to see.
Particle theory of matter
The instrument used to measure mass.
Balance
Matter that has definite volume but takes the shape of its container.
Liquid
The process of a solid turning directly into a gas without going through liquid state.
Sublimation
The transformation of energy from one form to another, like when wood burns to produce heat and light.
Energy Transformation
Newton’s first law is often restated as this “inertia” law.
Law of inertia
The tool used to measure temperature.
Thermometer
Matter that takes both the shape and volume of its container; particles are far apart.
Gas
A gas becoming a liquid.
Condensation
When energy can neither be created nor destroyed, only changed in form.
Law of conservation of energy
The principle that compares amounts of matter via balancing and that total mass remains same before and after a chemical reaction.
The conservation of mass in chemical reactions
The concept of the amount of substance in a given space: mass divided by volume.
Density
