change with temperature. As glucose is oxidised‚ oxygen is used up and carbon dioxide and heat energy is produced. Increment in temperature / production of CO2 or O2 consumption would hence be good indicators for the experiment. 1) Hypothesis [What other statements can I make‚ other the ones they mentioned about in the preview of the experiment?] 2) Procedures a) Weigh a mealworm and record its mass (0.61g). b) Set-up: Put 5 NaOH pellets into an Eppendorf tube.

In this lab‚ we will measure the heat of combustion‚ or calorimetry‚ of a candle and compare the found quantity with known values for other hydrocarbons. The calorific value is the total thermal energy released when a substance goes through complete combustion with oxygen. In order to achieve the purpose of this lab‚ we must first determine the mass of the tea candle. Then‚ we will determine our room temperature‚ measure about 100 mL of chilled water‚ and then pour the water into the given empty
