Ch. 1 Introduction to Matter

Anything that has mass and takes up space is called....

• homogeneous

• heterogeneous

• energy

• matter

What holds atoms together in a molecule?

• gravity

• density

• physical bonds

• chemical bonds

H2O, CO2, and C12 H22 O11 are all examples of chemical

• properties

• changes

• bonds

• formulas

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

• elements

• compounds

• mixtures

• atoms

The volume of an irregular object can be measured by

• multiplying the object's length, width, and height.

• multiplying the object's density by its mass.

• submerging the object in water in a graduated cylinder.

• placing the object on a triple-beam balance.

How do liquid water, ice, and water vapor differ from each other?

• They are different states of matter.

• They are different compounds.

• They are made of different kinds of molecules.

• They are made of different kinds of atoms.

One example of a physical change is

• burning paper

• baking cookies

• toasting marshmallows

• dissolving salt in water.

The ability to do work or cause change describes

• temperature

• density

• matter

• energy

One example of a chemical change is

• filtering a mixture

• burning wood

• boiling water

• crushing a can

Fireworks exploding in the sky and giving off light are an example of a(n)

• endothermic change

• exothermic change

• physical change

• change in mass
