A 25.0-g glass tumbler contains 200 mL of water at 24.0ºC. If two 15.0-g ice cubes, each at a temperature of –3.00ºC, are dropped into the tumbler, what is the final temperature of the drink? Neglect any heat transfer between the tumbler and the room. (Specific heat of water and ice are 4.186 kJ/(kg K) and 2.05 kJ/(kg K), respectively. The latent heat of fusion of water is 333.5 kJ/kg. The specific heat of glass is 0.840 kJ/(kg K )....

The density of water at 0°C is very nearly 1000 kg/m3 (it is actually 999.84 kg/m3), whereas the density of ice at 0°C is 917 kg/m3. The bulk modulus of ice is 2.20 × 109 Pa.    Calculate the pressure, in pascals, necessary to keep freezing water from expanding, neglecting the effect such a large pressure would have on the freezing point. (This problem gives you only an indication of how large the forces associated with freezing water might be.)
