A student is conducting an experiment using 3.4 g biodiesel, which is a very common type of biofuel. The student starts with an initial water temperature of 5°C.

Calculate the amount of thermal energy used to heat 102 g of water if the final temperature is 67°C. (The specific heat capacity of water is 4.18 J/(g °C)).

Calculate the heat of combustion for the sample of biodiesel the student burned. (Note that the heat of combustion is the quantity of thermal energy released when a certain amount of substance burns. Also, assume that all the energy released by the biodiesel is absorbed by the water.)
