. Water with a mass of 1000kg leaves a hose at 20oC and is converted by the heat from the fire into steam at 300oC. List the steps needed in order to determine the amount of heat that is added to the water. For each step show the formula that must be used and replace the variables with the appropriate numbers. Also, state whether the heat for each step will be positive or negative. You do not need to complete the calculations. Specific heat of water = 4.2 kJ/kgoC, Latent heat of vaporization of water = 2260 kJ/kg, Specific heat of steam = 2.0 kJ/kgoC
