1 Abdullah carried out an experiment to study the relationship between the rise in
temperature of water, and the mass of water, m . He measured 50 cm3 of water using
a measuring cylinder. Then he poured the water into a 1000 ml beaker. The
arrangement of the apparatus for the experiment is shown in Diagram 1.1.
Diagram 1.1
He measured the initial temperature of the water and recorded it as t0 = 25 C. Then he
switched on the power supply and stirred the water slowly. After 5 minutes he
switched off the power supply and continued to stir the water slowly until the
maximum temperature was reached as shown in Diagram 1.1.
He repeated the experiment using 60 cm3, 70 cm3, 80 cm3, and 90 cm3ofwater. The
maximum thermometer readings obtained are as shown in Diagram 1.2.
