• physical bonds

• chemical bonds

H2O and CO2 are examples of chemical

• properties

• charges

• 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 objects 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?

• different states of matter

• different compounds

• different kinds of molecules

• different kinds of atoms

One example of a physical change is
