Thermodynamics Virtual Labs and Investigations
All students must turn in their own paper.
Lab 1: •
http://www.7stones.com/Homepage/Publisher/Thermo1.html –Change volume, E, and molecules and observe what happens
Write observations, calculations, answers to questions down. What did you see? Was this what you expected? How do the laws of thermodynamics apply? Etc.
Lab 2:•
http://phet.colorado.edu/simulations/sims.php?sim=Reversible_Reactions –
Run simulation, change variables and observe what happens.
Write observations, calculations, answers to questions down. What did you see? Was this what you expected? How do the laws of thermodynamics apply? Etc.
Notice that you can adjust the height of each side of the reaction.
What do you think the ruler in the middle represents?
Move the middle bar to 50.
Move the reactant energy platform to 25. Keep the products on the lowest
possible setting.
Would you expect this reaction to be endo or exothermic? Why?
Add 50 particles to A.
Press start. Record what happens.
Attempt changes to the reaction conditions that will increase the amount of
product.(Record what you did and the results)
a) First change
Result.
b) Second change
Result.
Which change you made above would best simulate the addition of a catalyst to a
chemical reaction.
Now move the products to 25 and place the reactants at the lowest possible
setting. Start over with a new 50 particles. Record what happens. Would you
expect this to be more or less spontaneous? Why?
Lab 3:http://jersey.uoregon.edu/vlab/Thermodynamics/ –Read directions and do all 7 experiments
Write observations, calculations, answers to questions down. What did you see? Was this what you expected? How do the laws of thermodynamics apply? Etc.
