Question 1

N (number of molecules)

Answer 1

N= nNa
n: number of moles
Na: Avogadro’s number

Question 2

°C to K

Answer 2

+273

Question 3

∆W

Answer 3

∆W=p∆V
W: work
p : pressure
V: volume

Question 4

Number of moles

Answer 4

N= m÷Mr

Number of moles = mass ÷ relative formula mass

Question 5

What is the equation linking pressure and a constant?

Answer 5

pV÷T = constant

(pressure×volume)÷ temperature = a constant
