Problem

An electric kettle rated at 1.20×103 W1.20\times10^{3}\,\text{W} is used to heat 0.50 kg0.50\,\text{kg} of water initially at 20∘C20^{\circ}\text{C}. The specific heat capacity of water is 4.18×103 J kg−1 ∘C−14.18\times10^{3}\,\text{J}\,\text{kg}^{-1}\,^{\circ}\text{C}^{-1}. Assuming no energy losses, determine whether the water will reach its boiling point in 3.0 min3.0\,\text{min}. Provide a brief justification.
