The Calorimeter of Lavoisier and La Place
The Calorimeter of Lavoisier and La Place, Results Using an ice-calorimeter, Lavoisier proved that combustion and respiration were one and the same. He also measured the oxygen consumed during respiration and concluded that the amount changes depending on human activities: exercise, eating, fasting, and sitting in a warm or cold room. How did Lavoisier calorimeter work? The device consists of three chambers. Snow is placed in the outer chamber (providing insulation); a layer of ice is placed in the middle chamber; and a guinea pig is placed in the inner chamber. By measuring how much ice melted, Lavoisier was able to calculate how many calories the guinea pig was burning.
