particulate nature of matter

Question 1

arrangement of solids

Answer 1

closely packed in an orderly manner

Question 2

arrangement of liquid

Answer 2

closely packed in a disorderly manner and moving freely

Question 3

arrangement of gas

Answer 3

randomly spread very far apart from one another

Question 4

motion of solid

Answer 4

vibrating and rotating in their positions

Question 5

motion of liquid

Answer 5

Sliding over each other and moving freely about in their confined spaces throughout the liquid

Question 6

describe change in motion from solid to liquid

Answer 6

from vibrating and rotating about in their fixed solids as solids, to sliding over each other and moving freely about in their confined spaces throughout the liquid

Question 7

change in terms of distance of particles from liquid to solid

Answer 7

from being quite far to each other to being closely packed

Question 8

motion of gas particles

Answer 8

moving freely and rapidly in any direction from their confined spaces

Question 9

describe change in terms of motion of gas to liquid

Answer 9

from moving freely and rapidly in any direction away from their confined spaces to sliding over each other and moving freely about in their confined spaces throughout the liquid

Question 10

compare forces of attraction between solid, gas and liquid

Answer 10

the force of attraction between solids are very strong, while the forces of attraction between gas are very weak and the forces of attraction between liquids are moderately strong but weaker than solids

Question 11

what is diffusion

Answer 11

diffusion is the net movement of substances from a higher region of concentration to a lower region of concentration, down the concentration gradient, till equilibrium

Question 12

how does diffusion take place in on object W

Answer 12

when object W is not closed, the particles in W change into gas. As the concentration of W is at high concentration above W, they diffuse freely at high speeds in all directions
