Product Summary
The current and voltage sensors on the 850 Universal Interface's output are used to measure the electrical power delivered to the resistor that is heating the water and a Temperature Sensor is used to measure the increase in temperature of the water.
The amount of electrical energy used to heat the water is equal to the area under the power versus time curve. The amount of heat delivered to the water can be calculated using the increase in temperature and the mass of the water. The comparison of the electrical energy to the heat results in a value for the number of Joules in a calorie.
Concepts
- Compare electrical energy input to changes in internal energy
