Gas+Laws+and+Thermodynamics



A lab to determine the identity of a metal by its specific heat- Lots of ways to affect reaction rate-

Calorimeter labs- burn food and compare resuts to calories on package why are they the same or not?

Boil water (make tea) in a paper cup over a flame without burning the cup.

Use a vacuum pump or syringe and marshmallow- blow up the marshmallow Man- Rita Crush the can Balloon in the bottle- put balloons into two (thick non collapsing plastic) bottles so the balloon is inside and is stretched over the neck. You can blow your balloon up but a student can't. The secret- a tiny hole in your bottle

Zemek- this lab sucks

Rita- put a balloon over a flask- by putting the flask in clod and hot water you can expand and shrink the balloon. Ruler and newspaper demo – put a cheap yardstick (they pass them out for free at some hardware stores) under a sheet of newspaper flat on a table so the end of the stick sticks out about a foot. If you whack the end of the stick, the stick will break because air pressure of 14.7 psi is holding the newspaper down.

Coming soon- more detail on the labs below!

Manganese dioxide and hydrogen peroxide. Specific heat of metals lab- Pam Use Nickel spheres from Flinn for specific heat of metals- Rita Heat of vaporization- Pam wrap paper towel piece (6cm) around end of probe with rubber band to secure- goes slower for the heat of vaporization lab Rita two beaker demo Alicia- reaction rate lab- calcium carbonate I dilute acid-Pam Rita- chicken egg article.
