The graph below is the temperature vs time graph for 1.359 kg of water heated in a kettle of power 1800 W.From the equation from the graph ΔT/Δt = 0.308 Ks-1 = 4300 Jkg-1K-1Uncertainty in gradient = ± 0.001 Ks-1 (from the best fit line given in datastudio) - % uncertainty = 0.3%Uncertainty in m = ± 0.0001 kg (measured to nearest 0.1g) - % uncertainty = 0.01 %
