Let's say we have a beaker containing a mixture of liquid and solid water. The temperature for this mixture would be 0°C or 273K. 1. What will happen if it comes in contact with a metal block that is <273 K? 273 K 2. What will happen if it comes in contact with a metal block that is >273 K? >273 K Now let's think about the freezing process of the ice-water mixture. For each of the following state whether the thermodynamic term is: a) <0, b) >0, or c) 0 3. What would you predict for each of the following in terms of the system? a. AHsys b. ASsys 4. What would you predict for each of the following in terms of the surroundings? a. AHsurr b. ASsur 5. What would you predict happen? Recall the second law of thermodynamics) ASotal would be for this process? (Hint: does the process

A student determines the molar mass of a liquid unknown by the method used in thisexperiment. She found that the equilibrium temperature of a mixture of ice and water was1.0°C on her thermometer. When she added 12.3 g of her unknown sample to the mixture, thetemperature, after thorough stirring, fell to -4.0°C. She then poured off the solution through ascreen into a beaker. The mass of the solution was 93.4 g. Kf = 1.86°C/m  What was the molality of the unknown solution? ______________ m How much unknown liquid was in the decanted solution? ______________ gHow much water was in the decanted solution? ______________ gWhat did she find to be the molar mass of the unknown liquid, assuming she made thecalculation properly?______________ g

A mixture of phenol and water, under certain conditions of temperature and composition, forms two separate liquid phases, one rich in phenol and the other rich in water. At 30⁰ the compositions of the upper and lower layers are 70% and 9% by mass phenol, respectively. If 40kg of phenol and 60kg of water are mixed and the layers are allowed to separate at 30⁰C, what will be the weight of the two layers?

Estimate the freezing point (solidification temperature) of benzene at a pressure of 115 bar given that the enthalpy of fusion (AH,jus) of benzene is 9.94 kJ/mol. The corresponding densities of liquid and frozen benzene are 876 kg/m? and 894 kg/m? respectively.
