Answer

Brief Explanations:

  1. Can be compressed: Gases have large spaces between particles, allowing them to be compressed.
  2. Particles are arranged in an organized way: Solids have a regular, ordered particle - arrangement.
  3. Particles are very far apart: Gases have particles that are widely spaced.
  4. Fixed shape: Solids have a definite shape due to strong intermolecular forces holding particles in place.
  5. Variable volume: Gases and liquids can change volume depending on the container. Gases can expand to fill the container, and liquids take the shape of the container's bottom part.
  6. Particles slide past one another: Liquids have particles that can move relative to each other, allowing them to flow.
  7. Particles are arranged randomly: Liquids and gases have a more random particle - arrangement compared to solids.

For the second question, according to the kinetic - molecular theory, increasing the temperature of a gas causes the particles to move faster. Faster - moving particles collide more frequently and with greater force against the walls of the container, resulting in an increase in pressure.

Answer:
