Today, we briefly discussed the upcoming lab. When you come into class tomorrow, please have some ideas for designing an experiment to study the thermochemical properties (melting point, boiling point, heat capacity, heat of fusion, heat of vaporization) an unfamiliar material. (HINT: Think about making use of a familiar material to study an unfamiliar material.)
HW: In your journal, complete the following entry:
(1) Describe the difference between thermal energy and phase energy.
(2) In your own words, define melting point, boiling point, heat capacity, heat of fusion, and heat of vaporization.
(3) Write out the equations for energy required to raise the temperature of a substance, energy required to melt a substance, and energy required to vaporize a substance.
(4) Draw and explain the heating curve for ice at -10 degrees C to boiling water at 100 degrees C.
(5) Complete problem #2 from the challenge questions. [Ten (10.0g of ice at 0.00 degrees C was placed into 100.0g of water at 50.0 degrees C. What was the temperature after the ice had melted?]
