Answers
Answer:
1). The particle model of matter states that all matter is made up of tiny, moving particles with spaces between them. ... However, when the water and alcohol are mixed together, some of the particles of alcohol fit in between the particles of water.
2).Brownian motion refers to the random and erratic movement of microscopic particles that are suspended in any fluid, like water or oil.
3). Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration.
A familiar example is the perfume of a flower that quickly permeates the still air of a room.
4). The state of matter can change when the temperature changes. Generally, as the temperature rises, matter moves to a more active state. The word phase describes a physical state of matter, when a substance moves from phase to phase, it's still the same substance.
