Question 6

The apparatus shown in the diagram can be used to investigate the temperature rise produced in a known volume of water when a sample of propan-1-ol is burned.

Diagram showing a metal calorimeter can containing 150 cm³ of water supported by a clamp and stand. A thermometer is immersed in the water. A spirit burner containing propan-1-ol with a wick is positioned directly beneath the metal can.

The first steps of the method are:

  1. Place 150 cm3 of water into a metal calorimeter can.
  2. Measure and record the initial mass of the spirit burner containing propan-1-ol.
  3. Measure and record the starting temperature of the water.
  4. Position the spirit burner under the metal can and light the wick.

Describe the remaining steps of the method that are needed to determine the mass of propan-1-ol required to raise the temperature of the water by 20 ∘C20\text{ }^\circ\text{C}20 ∘C.
