Answer 1

Answer:

1) A common or traditional definition of matter is "anything that has mass and volume (occupies space)". For example, a car would be said to be made of matter, as it has mass and volume (occupies space). The observation that matter occupies space goes back to antiquity.

2)In a solid the particles fit very closely together. ... Because the particles are close together: they attract their neighbours - this is why solids tend to keep their own shape and to stay where they are put. solids are very difficult to compress - the gaps between particles are already very small

Answer 2

1. A common or traditional definition of matter is "anything that has mass and volume (occupies space)". For example, a car would be said to be made of matter, as it has mass and volume (occupies space). The observation that matter occupies space goes back to antiquity.
2. In a solid the particles fit very closely together. ... Because the particles are close together: they attract their neighbours - this is why solids tend to keep their own shape and to stay where they are put. solids are very difficult to compress - the gaps between particles are already very small
3. Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. ... gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
4. An atom is defined as the smallest individual particle of a matter. ... Then in 1897 when J J Thomson discovered electrons he stated that atoms are divisible. Then new subatomic particles proton, electron, and neutron were discovered so now atom is divisible.
5. Intermolecular forces are weaker attractions that hold molecules or noble gas particles close together when they are in a liquid or solid form. Gas particles have broken away from the intermolecular forces that hold liquids and solids together.
6. When a solute (like sugar or salt) is added to a definite volume of water, volume of water doesn't increase, only mass of liquid increases. Hence it proves that solute molecules have entered gaps present between water molecules.
7. The kinetic molecular theory of matter states that: Matter is made up of particles that are constantly moving. ... There are attractive forces between atoms/molecules, and these become stronger as the particles move closer together. These attractive forces are called intermolecular forces.
