Specific Heats and Atomic Masses Using a Calorimeter
Not what you're looking for?
ChemLab program "specific heat" lab.
Obtain 100 g shots of each: iron; copper & aluminum. Insert 150 ml of water at room temperature and heat to a
final temperature of 100 degrees of celsius.
Place in calorimeter and add 100 ml of water 20 degrees celsius.
Measure specific heat for each metal and atomic weight.
100 gm of each Fe; Cu; Al; initial temperature of each 20 degrees C; Final temp. of each 100 degrees C initial temp. of 100 ml of water; 20 degrees ; final temp of water in calorimeter: for Fe 28 degrees C; for Cu 27 degrees C; for Al 30 degrees C. determine specific heat for each metal and estimate atomic weight for each metal. Use 1 cal/gram *C for water.
