Math of Calorimetry

• Calorie
• Amount of energy needed to raise one gram of
  water 1? C
• Kcal formula on board
• Kcal / Gram
• Total Kcal measured in sample
• Change in mass of the sample

7

• Mass the whole apparatus before and after burning
• Foil, cork, pin, food/ash
• Using a scale
• on/tare allows the weight to go back to 0
• Dont let the thermometer rest on the bottom of
  the test tube
• Use a very small piece of walnut
• Dont let the water boil
• Keep the thermometer in the water while burning
• Use a different test tube each time (rotate them)

Calorimetry Lab

• Each person turns in their own lab
• Safety
• Jobs
• Masser
• Burner
• Temperature
• Each job should be rotated each time
• All math is computed on your own
