| Question | Answer |
|---|---|
| What does STP stand for? | Standard Temperature and Pressure |
| What is standard temperature and pressure, respectively? | Temperature: 273 K, Pressure: 1 atm |
| Who developed the mercury barometer? | Torricelli |
| 760 mm Hg = ? torr | 760 torr |
| 1 atm = ? mm Hg | 760 mm Hg |
| 760 mm Hg = ? psi (lb/in^2) | 14.7 psi |
| 1 atm = ? psi (lb/in^2) | 14.7 psi |
| 1 atm = ? Pa (Pascal; N/m^2) | 1.013 x 10^5 Pa (Pascal; N/m^2) |
| Charles' law: The volume of a gas is directly proportional to the absolute temperature of the gas at constant pressure and moles of gas. | V1/T1=V2/T2 Constant n (moles), P |
| Boyle's Law: The volume of a gas is inversely proportional to the pressure at constant moles and temperature. | P1•V1=P2•V2 Constant n, T |
| Gay-Lussac's Law: The pressure of a gas is directly proportional to the absolute temperature at constant moles and volume. | P1 = P2 T1 T2 Constant n, V |
| Combined gas law: | (P1•V1) |
