Hi, could I get some help with this work-heat-First Law of Thermodynamics physics problem involving calorimetry? The set up is: How many kilocalories (kcal) of heat are required to increase the temperature of one liter of water by 55 degree celsius (C) to 4 digits of precision, assuming the specific heat of water is 1 cal/gram K, with density of 1 g/cm3? Thank you.
