The ideal gas equation Flashcards
What is the volume of a gas influenced by?
The temperature and the pressure
What is Boyle’s law?
The product of pressure and volume is a constant as long as the temperature remains constant.
What is the calculation for Boyle’s law?
pressure x volume = constant
What is Charle’s law?
The volume is proportional to the temperature as long as the temperature remains constant.
What is the definition of constant?
a situation that does not change.
What are the equations for Charle’s law?
volume is (directly proportional to) temperature volume/temperature = constant
What is the constant volume law?
The pressure is proportional to the temperature as long as the volume remains constant
What is the equation for the constant volume law?
pressure (is directly proportional to) temperature pressure/temperature = constant
How do you work out the constant for a fixed mass of gas?
Pressure x volume/temperature = constant for a fixed mass of gas
What is the symbol for the gas constant?
R
What is the ideal gas equation?
pressure x volume = number of moles x gas constant x temperature or PV=nRT
What do you measure volume in?
