Solids Liquids and Gases

Question 1

What is the density of a material?

Answer 1

the mass per unit volume of material

Question 2

What is the equation used to calculate density?

Answer 2

density = mass / volume

Question 3

What is the equation for pressure?

Answer 3

pressure = force / area

Question 4

State an equation linking pressure difference, depth, density of liquid and gravitational field strength

Answer 4

pressure = depth * density * g

Question 5

How do you convert between Celcius and kelvin?

Answer 5

add 273

Question 6

What is absolute zero?

Answer 6

0 K - particles have no kinetic energy and do not move

Question 7

State an equation linking initial pressure, final pressure, initial temperature and final temperature

Answer 7

initial pressure / initial temperature = final pressure / final temperature

Question 8

State an equation linking initial pressure, initial volume, final pressure and final volume for a gas

Answer 8

initial pressure * initial volume = final pressure * final volume
