Question

Prelaboratory Assignment: Specific Heat Capacity 1. Technical objective. 2. What are the units for heat capacity, specific heat capacity, and molar heat capacity. 3. If a sample has an initial temperature of 22.15º and a final temperature of 18.45° C, what is AT? Is it any different in kelvin? A 100 g piece of metal, initially at 85° C is put (without heat loss or gain) into a cup with 50 g of water, initially at 22° C. Which of the following is true (select all that apply)? For the incorrect statements, explain why they are wrong. a. The temperature of the metal decreases and that of the water increases. b. The temperature change of the metal is equal but opposite that of the water. c. Q for the metal is equal but opposite that of the water. d. The heat capacity of the water is positive and that of the metal is negative.
