Question

the measure of particles in an object is ______.
○ mass
○ property
○ volume
○ dimension

Explanation:

To solve this, we analyze each option:

• "mass" is defined as the measure of the amount of matter (particles) in an object.
• "property" is a general term for characteristics of matter, not a specific measure of particles.
• "volume" measures the space an object occupies, not the amount of particles.
• "dimension" refers to measurable aspects like length, width, height, not particle amount.

So the correct option is the one that matches the definition of measuring particles in an object.

Answer:

A. mass
