Hypothesis: If you submerge heated marbles in a bath of water, then you will be able to find the temperature of the marbles.
Materials:
Materials:
- labquest
- beaker
- water
- styrofoam cup
- scale
- thermometer
- hot plate
- tongs
- Fill your beaker 1/2 of the way with water.
- Place the whole bag of marbles into the beaker and place it on the hot plate.
- Connect your thermometer to your labquest.
- Place your thermometer into the water and wait until it reaches 70 degrees Celsius.
- While you are waiting, use the scale to measure the mass of the styrofoam cup.
- Fill water 3/4 of the way in the styrofoam cup.
- Measure the initial temperature of the water and its mass.
- Once the beaker reaches 70 degrees Celsius, use the tongs to grab the beaker so you can drain it of all the water.
- Transfer just the marbles into the cup.
- Place the thermometer into the cup and allow the labquest to measure the change in temperature.
- Record you data.
Graph and AnalysisI chose to use a line graph to represent my data because it shows the trend of the temperature so it is easy to see the change. From this graph, I can see that the point of equilibrium was at 29.8 degrees Celsius. At first, the temperature of the water increased and then it plateaued. Finally, it decreased; this means that the water is losing heat to the environment.
