Water is in which phase when the pressure is 0.007 atm and thetemperature is (a) 95 degrees Celcius, (b) -10 degreesCelcius?
Homework Answers
Draw the phase diagram of the water and show the pressure and temperature points a and b on the figure to determine the phase of the water at the corresponding pressure and temperature.
from the above figure it is
clearly shows that the phase of water in part (a) is gas and in
part (b) is liquid.

Carbonated beverages are manufactured to dissolve carbon dioxide gas at high pressure that is released when the can is opened so that the beverage is more refreshing to the consumer. How many grams of dissolved carbon dioxide is in a 355mL can of soda at 20 degrees Celcius if the manufacturer used a pressure of 2.4 atm of CO2 to carbonate the pop? The Henry's law constant for carbon dioxide dissolving in water is 3.5*10-2 mol/L*atm at 20 degrees Celcius.

The solid/liquid phase transition of water near 1 atm external pressure is an important feature of our daily lives. Some relevant data concerning the transition include the density of liquid water at 273.15 K (0.999 g cm-3), the density of ice at 273.15 K (0.917 g cm-3), and the enthalpy of fusion of water at 273.15 K (6.008 kJ mol-1). (a) On a phase diagram, this transition appears as a line. Calculate the slope of this transition line near the...

5. A solid starting in phase a was heated at 1 atm pressure. Along the way to melting two solid-solid phase transitions occur at 1000 K (a → B) and 1500 K (B →y). When phase y is analyzed it is found to be the same as phase a. In other words phase a disappears at 1000 K only to reappear at 1500 K. a) How can this happpen? b) Which phase has the greater heat capacity?
