Formulae

Question 1

pressure

Answer 1

p=f/a
pressure = force/area

P₁V₁ = P₂V₂
when temperature is constant

P = pgh
pressure = density * gravity * height

Question 2

force

Answer 2

f = mv - mu / t
f = ma
force = mass * acceleration

Question 3

thermal capacity

Answer 3

Tc = m * c

thermal capacity = mass * specific heat capacity

Question 4

specific heat capacity

Answer 4

c = E/mΔt

Question 5

energy

Answer 5

E = Pt
energy = power * time
E = IVt
energy = current * voltage * time
E = ml
energy = mass * latent heat
E = mcΔt
E= tc * T
energy =  thermal capacity * temperature

Question 6

specific latent heat

Answer 6

specific latent heat = heat supplied to a substance / mass

l = E/m
