Question 1

how are particles in a solid arranged?

Answer 1

close together
strong forces
regular, fixed position/pattern
much energy
vibrations

Question 2

hw are particles in a liquid arranged?

Answer 2

close together in an irregular pattern
more energy than solid
move past each other in random directions at low speeds

Question 3

hoiw are particles in a gas arranged?

Answer 3

arent held close together
no forces between them
more energy than solids and liquids
move constantly at random directions and range of speeds

Question 4

what is density?

Answer 4

a measure of mass there is in a certain space

Question 5

what causes gas pressure?
explain how it can be increased

Answer 5

when particles collide, they hit the sides of the container and pressure is the force applied
an increase in the number of gas molecules in the same volume container increases pressure
