Particle model of matter

Question 1

equation

density

Answer 1

mass / volume

Question 2

Atoms in a solid

Answer 2

packed in ordered rows, vibrating
has a high density

Question 3

atoms in a liquid

Answer 3

less ordered, move around more
has a high density

Question 4

atoms in a gas

Answer 4

move randomly
low density

Question 5

measuring mass

regular solids

Answer 5

measured using a electronic balance

Question 6

measuring mass

irregular solids

Answer 6

measured by a displacment/eureka can

Question 7

measuring mass

liquids

Answer 7

total mass - mass of container

Question 8

latent heat

Answer 8

energy transferred to a substance when it change state

Question 9

internal energy

Answer 9

sum of kinetic and potential energy that make up a system

Question 10

heating a substance

Answer 10

increases temp - increases kinetic energy
changing state - increases potential energy

Question 11

specific latent heat

Answer 11

amount of energy transferred when 1kg of a substance changes state

no change in temp

Question 12

energy for change in state

Answer 12

mass x specific latent heat

Question 13

changing temp of gas

Answer 13

changes the pressure
