Liquid metallic zinc (Zn) has a vapor pressure of 40 torr at 673 C and 100 torr at 736 C. Predict the normal boiling point of zinc. can cause cancer. What is the vapor pressure of benzene at 24 C (about room tempera- ture)? The normal boiling point of benzene is 80 C and its molar heat of vaporization is 30.8 kJ/mol. It is found that 600 J of heat are required to melt 15 g of a compound. What is the heat of fusion of this compound? The specific heat of water is 1 . 00 cal / C, the heat of vaporization of water is 540 cal/g, and the heat of fusion of water is 80 cal/g. How much heat would be required to convert 10

Unformatted text preview: grams of ice at 0 ◦ C to 10 grams of water at 75 ◦ C? Consider an insulated system containing 100 g of liquid water and 100 g of ice at equi-librium under atmospheric pressure. A total of 12 g of steam at +110 ◦ C is admitted to the system. What is the phase composition and temperature when equilibrium is reestab-lished? Consider an insulated system containing 502 g of water at 25 ◦ C. Adding 193 g of ice at −10 ◦ C will result in equilibrium conditions with how many grams of ice at 0.0 ◦ C?...
