1) You have two cups of water. One is cold and one is hot. By predicting your thermometers to measure the temperatures. What do you think the temperature of hot water individually and cold water individually would be?

Temperature of hot water = _______ C

Temperature of cold water = ______ C

2) Now mix the two different temperature water together, By predicting your thermometers to measure the temperatures. What do you think the temperature of mixed water would be?

Actual final temperature = ______ C Time it took to reach a stable temperature: ______

3) The First Law of Thermodynamics is: Whenever heat flows into or out of a system, the gain or loss of thermal energy equals the amount of heat transferred. The Second Law of Thermodynamics is: Heat never spontaneously flows from a lower-temperature substance to a higher-temperature substance.

Explain how the investigations (two questions above) followed these laws of thermodynamics. 4) What is the difference between conduction and convection? Why might this difference matter in the time it takes to reach thermal equilibrium?
