Question

Heat losses are always a consideration in this type of experiment. How can these be reduced?

Heat of Combustion This activity compares the energy given out by liquid fuels by measuring the mass of each fuel that will heat a given volume of water to a given temperature. The fuels are burnt in a spirit burner which is weighed before and after heating the water. In general, the heat of combustion depends on the number of carbon atom. The higher the number of carbon atoms, the higher the heat of combustion. Also, the heat of combustion is greater for the hydrocarbons than for the alcohols.
