Background
In this experiment, you will add a hot piece of metal to room-temperature water
and measure the temperature change of the water. How does doubling the mass
of the added metal affect the temperature change?
Before You Begin
Start a new experiment on the GLX.
1.
Press
to go to the Home Screen.
2.
Use the arrow keys to highlight the Data Files icon and press
to open
the Data Files screen.
3.
Press
to open the Files menu and press
to select New File.
4.
When the GLX asks if you would like to save the previous file, press
to save or
not to save.
Procedure
Equipment Set-Up
1.
Fill a Styrofoam cup with hot water.
2.
Tie a string to each mass, and lower all three masses into the hot water. Let
the masses warm up for about 10 minutes.
3.
Label two other cups “Cup 1” and “Cup 2.” Put 250 ml of room-temperature
water into each cup.
4.
Put one temperature probe in each cup of room-temperature water. Use a
paperclip to secure each probe to the rim of the cup so that the end of the
probe is about midway between the bottom and the surface of the water.
