How to measure the power of dry ice sublimation

[Aofferle]

I really need an idea or a name of a machine the will enable me to measure the power of dry ice sublimation. Please post an answer before March, 2nd

When I first read your question, I didn't know what you meant when you asked about "the power of dry ice sublimation". But I did some surfing on the web and found a couple sites that gave me a clue.

I think you're talking about doing something like what appears on one of these sites:
http://www.west.net/~science/co2.htm

I imagine you think that if all this CO2 gas is being emitted during the sublimation, then perhaps it can be turned into power to do something.

First, let's figure out what "power" is. "Power" is the rate at which work is performed, or how much work is done over a specific length of time. "Work" is equal to the force acting on an object times its displacement (how far the object moves while the force acts on it). So to be able to measure the "power" of dry ice sublimation, you will need to set up an experiment that can measure three things: force, distance and time.

You would need to get creative and figure out how to cause the gas released by the dry ice to move something, like a pinwheel maybe, or a piston in a tube, and measure how fast the object moved, how far, and how much force was involved.

This could be a very interesting experiment, but it will take a lot of thinking on your part.

I hope you have fun with this one.
