water is set on the stove to boil as it absorbs the temperature increases from 27.5°C to 56.0°C. if there was 325g of water added to the pot, how much energy was absorbed if the heat capacity of water is 4.18J/°C? Round answer to the correct number of significant figures.

325g x 4.18 x 28.5 = 38717.25J= 387KJ (3sf)
