1 Butanol is a liquid fuel.
A student investigated the mass of butanol needed to increase the temperature of
100 cm3 of water by 1 °C.
The student used the following method.
step 1 add 100 cm3 of water to a beaker
step 2 measure the mass of a spirit burner containing butanol
step 3 measure the initial temperature of the water in the beaker
step 4 place the spirit burner containing butanol under the beaker of water
step 5 light the wick of the burner and start to stir the water with the thermometer
step 6 stop heating the water when the temperature of the water has increased
by 30 °C
step 7 remeasure the mass of the spirit burner containing butanol.
Figure 1 shows the apparatus used.

(b) The student investigated the effect of changing the fuel on the mass of fuel
needed to heat the water.
The student used an identical spirit burner filled with pentanol, another
liquid fuel.
Give two variables that the student should keep the same in this investigation.
