Answer 1

1) Strong forces of attraction held close together in a fixed regular arrangement
2) vibrate about fixed position
3) density is highest as particles close together

Question 2

Liquid?

Answer 2

1) Weak forces of attraction
2) irregular arrangements
3) move in random directions in low speeds
4) less dense

Question 3

Answer 3

1) free to move
2) random directions high speeds
3) low density

Question 4

How to find density of a liquid?

Answer 4

1) Place measuring cylinder on a balance and zero the balance
2) Pour 10ml into cylinder and record liquid’s mass
3) Pour another 10 ml into cylinder and record total volume and mass repeat until full
4) for each measurement use formula to find density
5) average
