Introduction to Matter

(IC Chapter 1 Test)

The ability to do work or cause change describes this.

energy

Burning wood is this type of change.

chemical change

Anything that had mass and takes up space.

matter

Fireworks exploding in the sky and giving off light are examples of this kind of change.

exothermic change

The fact that matter is not created or destroyed in any chemical or physical change is this.

law of conservation of mass

A change in matter that produces one or more new substances.

chemical change

Length x width x height is how you find this measurement.

volume

Hardness, texture, color, and freezing point are examples of this.

physical property

This is how liquid water, ice, and water vapor differ from each other.

they are different states of matter

This holds atoms together in a molecule.

chemical bond

Soil, a salad, and sugar water are all examples of this.

mixture

This is how the volume of an irregular object can be measured.

submerging the object in water in a graduated cylinder

A single kind of matter that has a specific composition.

substance

A change in which energy is absorbed.

endothermic change

H2O, CO2, and C12H22O11 are all examples of this.

chemical formula

A substance that undergoes this type of change is still the same substance after the change.

physical change

The process by which molecules at the surface of a liquid absorb enough energy to change to a gas.

evaporation

The smallest particle of an element.

atom

A measure of the mass of a material in a given volume.

density

Dissolving salt in water is one example of this type of change.

physical change

This is a group of two or more atoms that are held together by chemical bonds.

molecule

This is formed when two or more substances are so evenly mixed that you can’t see the different parts.

homogeneous mixture

The volume of 50 milliliters is the same as a volume of this many cubic centimeters.
