Temperature Change With Compounds NaCl & CaCl By Kirsten, Eric, and Matt
Question: • What happens to the temperature when a solute dissolves in a solvent?
Materials: NaCl Graduated Cylinder Temperature Sensor Computer Foam Cup
What Are The Variables In This Lab? The independent variable is the amount of sodium chloride in grams. The dependent variable is the temperature.
What Stayed The Same In The Lab? • The type of solute (NaCl and CaCl). • The styrofoam cup. • The amount of water (50 mL). • The equipment we used (temperature sensor, computer, and graduated cylinder).
Conclusion According to the data, the temperature decreased when NaCl was added, and increased when CaCl2 was added. The data from the virtual lab and the data from our lab was closely related. When more NaCl was added to the solvent, the temperature of the solution decreased by a rate of about .5 degrees per gram. As the more CaCl2 was added, the solution increased by a rate of about 1.3 degrees per gram. Our hypothesis was supported throughout the lab. As we stated before, the CaCl2
