Heat Transfer with Prediction Lab
In this lab you will be looking at the connection between the thickness of a barrier and the rate at which energy passes through the barrier. Once you have established your relationship, you will be using it to make predictions on things you haven't tested.
The hot and cold chambers are held at their original temperatures even as energy is exchanged between them.

Create a graph with speed (m/s) obtained by the astronaut on the y-axis and the time of fire on the x-axis.Enter the slope below and then use the equation you discovered to find the speed created if the astronaut fired the extinguisher for x seconds.Finally, find the thrust of the fire extinguisher by multiplying the slope of your graph by the mass of the astronaut.
