Day 3

*can was heated up side down (with vapor in it) this caused it to implode when it was put into the water. when it was heated facing up, then nothing happened to the can

*This is a vacuum chamber. decreasing the pressure cause the volume of the balloon to increas

* volume of the marshmallow increased also, except when deflated they shrunk smaller than the norml size

We learn experimentally about the effects pressure can have on containers of gas and  we learned how to calculate buoyancy and ideal gas problems.
