2 Chemistry Gas Unit
Chemistry Gas Unit Grade 11 sides 2 and 3
| Question | Answer |
|---|---|
| Boyle’s Law | -temperature and number of moles held constant - inverse relationship between the pressure and the volume of a gas -As the volume increases, the pressure decreases and vice versa P1V1 = P2V2 |
| Charles' Law | -pressure and number of moles of gas is held constant -direct relationship between the volume of a gas and its temperature - KEEP THE TEMPERATURE IN KELVIN -As temperature increases, volume increases V1/T1= V2/T2 |
| Gay-Lussac’s Law | - volume and number of moles of a gas are held constant, direct relationship between the pressure and temperature of gas -KEEP THE TEMPERATURE IN KELVIN -pressure increases, temperature increases if volume is held constant. -P1/T1= P2/T2 |
| Combined Gas Law | Temperature should be kept in Kelvin (P1/V1)/T1=(P2/V2)/T2 |
| PV=nRT | P = pressure (in kPa or atm) V = volume (in L) n = number of moles T = temperature (in K) R = universal gas constant (diff units depending on pressure you use) |
| Universal Gas Constant | R: 1)8.314( L*kPa/mol * k) |
