Gay-Lussac's+Law

Gay-Lussac ’ s Law

In this law it shows the relationship between pressure and temperature and shows that as temperature increases so does the pressure.

Here is what the equation looks like: P1/ T1= P2/ T2

Just like all the other laws you are going to want to solve for the variable that you are looking for. An example would be if you were looking for T2 you would multiply each side by P2 and you would be able to find T2.

Here is an example problem: Say you have a pressure on something of 4 atm and the temperature is at 100 degrees then after a while the temperature increases to 200 degrees. What is the new pressure?

 v  First what you would is state what your givens are in this case your givens are:

Pressure 1: 4atm Temperature 1: 100 degrees Pressure 2: ? Temperature 2: 200 degrees

 v  Next make the new equation depending on what variable you are looking for in this case you are looking for P2 so the eqaution would look like this:

P1T2 / T1

 v  Then you are going to place your numbers in the equation this is what it would look like:

4atm x 200 degrees / 100 degrees = P2

 v  Finally you are going to solve the equation and get your answer the answer would be:

8atm
