Question | Answer |
---|---|
Pressure | The force per unit area exerted on an object. |
Pressure formula | P = F/A P = pressure F = force A = area |
Pascal (Pa) | Newtons/m² |
1.000 atm | 101.3 kPa 760.0 mmHg 760.0 torr |
Boyle's Law | PV = constant P₁V₁ = P₂V₂ |
Charles's Law | V/T = constant V₁/T₁ = V₂/T₂ |
Extrapolation | Following an established trend in the data even though there is no data available for that region |
Combined Gas Law | P₁V₁/T₁ = P₂V₂/T₂ MUST use the Kelvin temperature scale |
Ideal gas property | 1 |
Ideal gas property | 2 |
Ideal gas property | 3 |
Standard Temperature and Pressure (STP) | Temperature = 273 K Pressure = 1.00 atm |
Dalton's Law of Partial Pressure | When two or more ideal gases are mixed together, the total pressure of the mixture is equal to the sum of the pressures of each individual gas. P(T) = P₁ + P₂ + P₃ + ... |
The pressure of an ideal gas depends on ... | the quantity of that gas |
Vapor Pressure | The pressure exerted by the vapor which sits on top of any liquid |
The vapor pressure of any liquid (increases, decreases) with increasing temperature | increases |
Boiling point | The temperature at which the vapor pressure of a liquid is equal to normal atmospheric pressure |
Mole fraction | X = |
Dalton's Law with mole fractions | P₁ = X₁P(T) |
Ideal Gas Law | PV = nRT R = 0.821 L*atm/mole*K n = |
