P / T = P / T
Again, the temperature must be in Kelvins! There cannot be negative or zero temperatures, so the Kelvin scale is used.
Kelvin = Celsius degrees + 273
Here's a problem solving video:
I never performed a classroom lab based on this gas law, but here is a cute demonstration:
BTW, Kelvins are not reported with degrees (as the student did) -- it's an easy mistake to make.
Many labs use calculator-based pressure sensors -- not everybody has access to that, so I'm not posting those type of labs here. If your department has them, your department probably has a lab procedure that already has been used. If not, here's your chance to set a precedent! Go for it!
And, check out my lab book "Chemistry on a Budget" at:
Each lab is presented with two possible report formats -- both with the same procedure -- one with 10 questions to be answered as a conclusion, the other with a full laboratory report required. This was to give the teacher the option of what type of report is desired!
*I'd love to hear about your experiences or if you have ideas for other topics for this blog.
Have a good week!
