Aim:

To measure and compare the enthalpy change of combustion for four different types of fuels by burning them and measuring the increase in the temperature of water in a calorimeter.

From the increase in temperature of a known mass of water it is possible to calculate the enthalpy change of combustion (?Hc) for the fuels by the following formula

Energy transfer = mass x Specific Heat Capacity x ?T joules

Where ?T = the change in temperature in degrees Kelvin.

The specific heat capacity of water is 4,2 J g-1 K-1 (Cambridge Chemistry 1). The specific heat capacity means the amount of energy required to raise 1 gram of water 1o C.

The enthalpy change of combustion is when 1 mole of substance reacts completely with oxygen under standard conditions.

Apparatus:

> Small copper can which acts as a calorimeter, (base diameter 10cm).

> 0-1100C thermometer

> 100cm3 measuring cylinder

> Spirit burners containing -methanol, ethanol, propan-1-ol and butan-1-ol.

> Access to a weighing balance (2 d.p)

> Draught shields

Method:

> Use
