CHEM 1 Test Review

Which of the following statements is true about an object’s weight, but NOT about its mass?

• It may vary depending on the object’s location.

• It is a measure of the amount of matter in the object.

• It is measured in kilograms or grams.

• It would be the same on the moon as it is on Earth.

The larger an object’s mass, the

• smaller its inertia.

• larger its volume.

• larger its inertia.

• smaller its volume.

Which of the following are physical properties?

• Color, shape, and flammability.

• Size, shape, and supports combustion.

• Color, size, and reacts with an acid.

• Color, density, and odor.

Why are chemical properties harder to observe than physical properties?

• Chemical properties change the substance’s identity.

• Chemical properties depend on the size of the sample.

• Physical properties cannot be observed and measured.

Boiling point, melting point and density are some of an elements

• nonreactive properties.

• physical properties.

• chemical properties.

• pure properties.
