C. It has mass and volume
Explanation:
Every atom of an element has mass and volume. Mass is the amount of substance it contains this is usually a function of their subatomic particles.
The bulk of the mass of an atom is concentrated in the nucleus where we have protons and neutrons. Electrons do not really add much to the mass of an atom.
Atoms also have specific volume.
- The reason for our selection is that atoms are the smallest particle of matter.
- Matter is anything that has weight and occupies space.
- Since it is matter, it must have specific weight and volume

Answer:
Explanation:
Figure 6. An instant cold pack consists of a bag containing solid ammonium nitrate and a second bag of water. When the bag of water is broken, the pack becomes cold because the dissolution of ammonium nitrate is an endothermic process that removes thermal energy from the water.
Answer:
because weight depends on the gravity, gravity decrease s with increasing altitude,hence I have less weight
