Constants Periodic Table Heat, q, is energy transferred between a system and its surroundings. For a process that involves a temperature change Part A q= m C, AT where C, is specific heat and m is mass. Heat can also be transferred at a constant temperature when there is a change in state. For a process that involves a phase change Calculate the enthalpy change, AH, for the process in which 10.0 g of water is converted from liquid at 0.3 C to vapor at 25.0 °C. For water, AHvap = 44.0 kJ/mol at 25.0 "C and C =4.18 J/(g- "C) for H2O(1). Express your answer to three significant figures and include the appropriate units. g=n AH where, n is the number of moles and AH is the enthalpy of fusion, vaporization, or sublimation. > View Available Hint(s) The following table provides the specific heat and enthalpy changes for water and ice.
