Kinetic Theory (unit 2) Equations

Question 0

Specific latent heat of fusion = ?

Answer 0

Specific latent heat = total heat supplied / mass

L = Q / m

L = specific latent heat (J/kg or J/g)
Q = total heat energy supplied (J)
m = mass (kg or g)

Question 1

Boyle’s law = ?

Answer 1

Pressure * volume = constant

Pressure and volume are inversely proportional

P1V1 = P2V2

v = velocity (m/s)
P = pressure

Question 2

Specific heat capacity equation

Answer 2

Q = m * C * delta T

(need to rearrange it)

C = specific heat capacity (J/kg/degree C)
Q = heat energy supplied (J)
m = mass (kg)
Delta T = change in temperature (degree C)

Question 3

Specific latent heat of vaporisation

Answer 3

Lv = Q / m

Question 4

Pressure = ?

Answer 4

Pressure = force / area

P = F / A

P = pressure (Pa)
F = force (N)
A = area (m^2)
