DF - Gas volumes Flashcards
What volume does 1 mole of any gas have at room temperature and pressure (RTP)?
24dm^3
What are the values for RTP?
298K (25 degrees celsius) and 100kPa.
What is the ideal gas equation?
pV=nRT
What do the components of the ideal gas equation stand for?
pV=nRT
p= pressure (Pa) V= volume (m^3) n= number of moles R= 8.314 J K^-1 mol^-1 (gas constant) T= Temperature (K)
What does the ideal gas equation let you find out?
The number of moles in a certain volume at any temperature and pressure.
How do you convert from celsius to kelvin?
+273
What piece of apparatus can be used to measure gas volume?
A gas syringe attached to the opening of a reaction vessel lets you measure how much gas is produced in a reaction.
How can you tell when measuring gas volumes using a gas syringe, that the reaction has ended?
There will be no further change in gas volume.
What can really vigorous reactions do to a gas syringe?
Blow the plunger out so you have to be careful.
