Thermal Expansion and Phase Change Lab

The torch was used to heat up a metal ring, so it would expand and allow the metal ball to pass through it.

Water was boiled and the steam was passed through the metal rod, so it would expand and cause the rotational sensor to rotate.

                                   

The torch was used to heat up the metal strip, that was made up of two different metals, and see which way the strip would bend.

Ice was added to hot water and was mixed with a temperature sensor to see what happens as the ice melts.

This graph shows that the temperature rose  at a constant rate as the ice was melting.

These graphs show that the metal rod expanded and caused the rotational sensor to rotate as is got hotter.

                           

We experimented with thermal expansion by heating up a metal ring to see if a metal ball would pass though it, and heated up a metal rod with steam to see if it would rotate the rotational sensor it was on. Then we went over the math of phase changes and what actually happens during a phase change. We ended by going over a little on pressure and volume.
