Calorimetry

• what is and what are you finding for formula 1 in calorimetry?

  you are finding the Energy Given Off By food

  energy= volume of water*4.2* Temperature rise of water
• What is and what are you finding for formula 2 in calorimetry?

  you are finding the energy content per gram of food

  Energy Content= energy given off by food (formula 1)/ Mass of food
• What is and what are your finding for formula 3 in calorimetry?

  you are finding the energy content in KJ(J/1000)

  Formula 2 Answer/1000
• Calorimetry Steps:

  • Measure start temperature of water(in a test tube)
  • Measure the start mass of the food
  • The food is placed below the test tube and set on fire
  • The temperature of the water after the food is fully burnt is measured and temperature difference is calculated
• Calorimetry

  • the energy released from the food by burning is transferred to the water
  • As the water gains energy the temperature increases
