The specific heat capacity of water is the amount of energy (in Joules) required to raise the temperature of 1 kg of water by 1 °C; for practical purposes, this is equal to about 4186 J/(kg∙°C). Estimate the amount of time in seconds required to raise the temperature of 1 L of water from 0 °C to 100 °C for an electric hot plate (rated at 1200 W and efficiency of 40%). Assume that the density of water is ρ=1 kg/L. Question 3 options: 349 s 418 s 1200 s 872 s
