17N.3.SL.TZ0.1c.i
In an experiment, data were collected on the variation of specific heat capacity of water with temperature. The graph of the plotted data is shown.
The uncertainty in the values for specific heat capacity is 5%.
Water of mass (100 ± 2) g is heated from (75.0 ± 0.5) °C to (85.0 ± 0.5) °C.
(c.i)
Calculate the energy required to raise the temperature of the water from 75 °C to 85 °C.
