Answer 1

Answer:

1. Matter is everything around you. Atoms and compounds are all made of very small parts of matter. Those atoms go on to build the things you see and touch every day. Matter is defined as anything that has mass and takes up space (it has volume). ... Volume is the amount of space something occupies.
2. Solid, liquid and gas
3. solid:--table sugar, water ice, frozen carbon dioxide (dry ice), glass, rock, most metals,

Liquid:--Water, Milk, Blood, Urine, Gasoline.

Gas:--, nitrogen, oxygen, fluorine, chlorine, helium,

4. Solids have a fixed shape and a fixed size. The particles are very close together and held in place by strong forces (bonds). Their particles cannot move around, but they do vibrate. Because the particles cannot move around, a solid has a fixed shape.
