10/24 – Monday “A” Day  

Main focus: 

1. To calculate the Joules of energy absorbed by a block dropped in hot water.
2. To Calculate the Joules of energy released by water if a cold metal block is placed in the hot water.
3. To review the basic principle of calorimetry.
 
1.  Classwork Calorimetry Problem – 
 
Calorimetry Metal Block problems 1
 
a) In what direction was energy moving?
b) How does temperature change with this flow of thermal energy?
c) How does the energy measures from the metal block and water compare?
d) Why is there such a large difference in temperature change between the metal and the water if the energy lost and gained are the same?
e) What does a large or small specific heat quantify?
