what is an “ideal gas”
a gas where there are no forces between the particles
what is the ideal gas equation
PV = nRT
P = pressure (Pa)
V = volume (m3)
n = number of moles
R = gas constant (mol-1 K-1) (always given)
T = temperature (K)
Converting volume into SI units
dm3 × 10-3 = m3
cm3 × 10-6 = m3
Converting pressure into SI units
kPa x 103 = Pa
MPa x 106 = Pa
Converting temperature into SI units
°C + 273 = K
