A student designs an experiment to determine the specific latent heat of fusion of ice. Crushed ice at 0 ∘C0\text{ }^\circ\text{C}0 ∘C is placed inside a funnel around an electrical immersion heater, and the mass of meltwater collected in a beaker is recorded.
Identify one significant source of systematic error in this experimental setup and state how a control setup can be used to reduce its effect on the final calculated value.
