- What quantity of energy does it take to convert 0.500 kg ice at 20.C to steam at 250.C? Specific heat capacities: ice, 2.03 J/g C; liquid, 4.2 J/g . C; steam, 2.0 J/g C; Hvap = 40.7 kJ/mol; Hfus = 6.02 kJ/mol.arrow_forwardThe enthalpy of vaporization of water is larger than its enthalpy of fusion. Explain why.arrow_forwardLiquid butane, C4H10, is stored in cylinders to be used as a fuel. Suppose 35.5 g of butane gas is removed from a cylinder. How much heat must be provided to vaporize this much gas? The heat of vaporization of butane is 21.3 kJ/mol.arrow_forward
- Explain why the enthalpies of vaporization of the following substances increase in the order CH4NH3H2O, even though all three substances have approximately the same molar mass.arrow_forwardHow much heat is required to convert 422 g of liquid H2O at 23.5 C into steam at 150 C?arrow_forwardWhy are steam burns so much worse than water burns even if the H2O is at the same temperature for both phases? Hint: Consider the heat of vaporization of water.arrow_forward
- Calculate the quantity of heating required to convert the water in four ice cubes (60.1 g each) from H2O(s) at 0 °C to H2O(g) at 100. °C. The enthalpy of fusion of ice is 333 J/g and the enthalpy of vaporization of liquid water is 2260 J/g.arrow_forwardFollow the step-wise process outlined in Problem 31 to calculate the amount of heat involved in condensing 100.00 g of benzene gas (C6H6) at 80.00C to liquid benzene at 25.00C. Use Tables 8.1 and 8.2 for the specific heat, boiling point, and heat of vaporization of benzene.arrow_forwardCalculate the grams of oxygen gas required to produce 7.60 kJ of heat when hydrogen gas burns at constant pressure to give liquid water, given the following: 2H2(g)+O2(g)2H2O(g);H=484kJ Liquid water has a heat of vaporization of 44.0 kJ per mole at 25C.arrow_forward
- Consider the phase diagram and heating-curve graphs for Question 113. Draw corresponding heating curves for T1 to T2 at pressures P1 and P2. Label each phase and phase change on your heating curves.arrow_forwardThe cooling effect of alcohol on the skin is due to its evaporation. Calculate the heat of vaporization of ethanol (ethyl alcohol), C2H5OH. C2H5OH(l)C2H5OH(g);H=? The standard enthalpy of formation of C2H5OH(l) is 277.7 kJ/mol and that of C2H5OH(g) is 235.1 kJ/mol.arrow_forward
