5 Solids liquids and gases Flashcards
1
Q
What is the density formula?
A
Density = mass / volume
2
Q
What is the pressure formula?
A
Pressure = Force (N) / area (sqm)
3
Q
What is the pressure difference formula
A
p = h x ρ x g
4
Q
What was Boyle’s law?
A
P1 x V1 = P2 x V2
5
Q
What assumptions do we have to make whilst using Boyle’s law?
A
That the temperature is constant and there is a fixed mass of gas
6
Q
Celsius –> Kelvin?
A
0 degrees C –> + 273 degrees Kelvin
7
Q
Kelvin –> celcius?
A
0 Kelvin –> - 273 degrees C
8
Q
How do we measure a fixed gas at a constant volume? (formula)
A
P1/T1 = P2/T2
