Question

identify the choice that best completes the statement or answers the question. 1. __________ is best described as the amount of mass per unit of volume a. matter b. density c. volume d. mass 2. __________ is the quantity of matter in an object a. volume b. density c. weight d. mass

Explanation:

1. Density is defined as mass per unit volume. Matter is anything that has mass and takes up space. Volume is the amount of space an object occupies. Mass is a measure of the amount of matter in an object. So the answer for 1 is density.
2. Mass is the quantity of matter in an object. Volume is space - related, density is mass per unit volume, and weight is the force exerted on an object due to gravity. So the answer for 2 is mass.

Answer:

1. b. Density
2. d. Mass
