Gas laws is continued this week with a lesson called “Ideal Gas Law.”     Combining Boyle, Charles’ and Gay-Lussec’s laws, into one law…making it possible for us to predict one variable (pressure, volume, number of moles, or temperature) if we are given the other variables.  

 The relationship between these variables also includes R (the Gas Constant).  This constant helps us calculate and predict conditions for the gas.  

The relationship between these variables is expressed in the following equation: 

PV = nRT

P = gas pressure in atmospheres

V = volume in Liters

n = # of moles of gas

R = The Gas Constant 

T = Temperature in degrees Kelvin

The simulation this week on Gizmo is excellent at helping us discovering the relationship between these variables.   

Think about what happens in your experiences in real life as you go through the simulation. 

 Where have I seen this before?   How am I affected by these types of changes? 

FYI:        Next Monday is Memorial Day.  We have NO SCHOOL on this Friday or Next Monday.   That means that you need to get this week’s work in BEFORE you go on (mental) vaca for the long weekend.   I am leaving the due dates in ILearn as still 10 am Friday, May 22nd.   I will still post next week’s work by Sunday, noon.   I don’t expect you (or me!) to work over the looooong weekend!  But I will post the work, just in case you get bored : )

Stay safe and well!
