Lesson details

Lesson outcome

I can analyse calorimetry data to determine which alcohol releases the most energy when combusted.

Show transcript
Calorimetry can be used to measure a reaction's energy change indirectly. Calorimetry data can be used to calculate the mass of alcohol needed to cause a 1°C rise in temperature of the water. An alcohol that causes a 1°C temperature rise when the least amount is combusted is releasing the most energy. The energy change of combustion for a variety of alcohols can be compared to the molecular formula of each alcohol.
