Part A Heat, q, is energy transferred between a system and its surroundings. For a process that involves a temperature change q=m.CAT 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 36.2 g of water is converted from liquid at 14.2 C to vapor at 25.0 C. For water, AH vap = 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. q= - ? AH = Value Units where, n is the number of moles and AH is the enthalpy of fusion, vaporization, or sublimation. The following table provides the specific heat and enthalpy changes for water and ice. Substance Specific heat AH [J/g.C)] (kJ/mol) water 4.18 44.0 Submit Request Answer ice 2.01 6.01 Part B How many grams of ice at -9.1 C can be completely converted to liquid at 19.7 C if the available heat for this process is 4.36x103 kJ ? For ice, use a specific heat of 2.01 J/(g.C) and AHfus = 6.01kJ/mol Express your answer to three significant figures and include the appropriate units. ?
