7.1 Assume that the density of solid water is 920 kg m-3 and that of liquid water is 1000 kg m-3. Calculate the change of the melting temperature, T, of ice for the process of changing pressure from 100 kPa to 1850 kPa. Use fusH = 6010 J mol-1 for water.

7.2 At two temperatures, 85 K and 135 K, the vapor pressures of a certain liquid were found to be 540 Torr and 830 Torr, respectively. From this information, determine the molar enthalpy of vaporization, vapH. (Assume pV = nRT for the vapor and a temperature independent vapH.)

Liquid water at 293 K and 1.8 kg/s is mixed with steam at 573K in a heating chamber. The water leaves the chamber at 300 kPa and 333K. Determine the mass flow rate of the steam. Where it exists in such a state, you may assume compressed liquid to have the same properties as saturated liquid at that temperature.

1 kg of water in a piston cylinder arrangement is initially in a saturated liquid state at 1 bar. It undergoes expansion at constant pressure due to external heat supply to it, to a final state of saturated vapor. (i) What is the initial temperature of water in C? (a) 93.50 (b) 96.71 (c) 99.63 (d) 111.4 (e) 12.2 (ii) What is the change in enthalpy of water (kJ/kg-K)? (a) 417.46 (b) 2258.0 (c) 2675.5 (d) 2506.1 (iii) What is...

c (water) = 4190 j/kg•K density of water = 1000 kg/m^3 In Wakanda, at the Vibranium Institute of Energy Research, the sister of the Black Panther, Shuri has found a way to generate energy from the gradient in temperature of Lake Malawi. At some large depth the temperature of the water is 7.2 degrees C while at the surface it is 26.8 degrees C. (a) The maximum theoretical efficiency of the research power plant is? (b) It is hoped that...

1. a. How many kilograms of water can be evaporated from a 1 m^2 surface of water in a lake on a hot, clear summer day, if it is assumed that the limiting factor is the Sun’s heat of 1800 J s^-1 m^-2 for an 8-hour day? Assume that the air and water temperatures remain constant at 40C. b. What volume of air is needed to hold this much water vapor at 40C? c. When the Sun sets, the air...

A water drop slung onto a skillet with a temperature between 100°C and 200°C will remain a liquid for about 1 second. However, if the skillet is much hotter the drop can last several minutes. This is due to the Leidenfrost Effect, named after an early investigator (circa 1756). The longer lifetime is due to the support of a thin layer of air and water vapor that separates the drop from the metal (by a distance L, as shown in...
