Metric Test Review

Why do scientists prefer measuring the mass of objects rather than the weight?

• The mass of an object tends to remain unchanged everywhere in the universe

• Mass changes too much with motion and location

What is the volume of the block with all side lengths 2.5 cm to the nearest tenth of a unit?

• 2.5 cm

• 16 cm3

• 15.6 cm3

• 7.5 cm3

Mass is a measurement of

• the amount of space occupied by an object

• the amount of matter in an object

• the average particle speed of an object's molecules (average molecular kinetic energy)

• the amount of gravitational force on an object

Temperature is best described as a measurement of

• the amount of matter in an object

• the average particle speed of an object's molecules (average molecular kinetic energy) 

• heat

• the average distance between two molecules

Which of the following is a quantitative statement?

• For every 2 degree C increase in temperature, the metal rod became 1 mm longer.

• The mass of the mineral sample depended upon the volume of the sample.

• In the experiment, tulips grew taller than the roses.

• When more air was forced into the balloon, the pressure inside the balloon increased.
