How much heat (in kJ) is required to convert 100 g of ice (H2O) at 253 K to steam (H2O) at 393 K? Assume the following values: specific heat of ice = 2.09 J/g·K, specific heat of liquid water = 4.18 J/g·K, specific heat of steam = 2.01 J/g·K, enthalpy of fusion = 334 J/g, enthalpy of vaporization = 2260 J/g.
