The normal boiling point temperature (pressure of 1 atm) will be higher for an aqueous solution of an ionic compound relative to that of pure liquid water. The boiling point is higher because the solution has a lower vapor pressure at the same temperature, due to stronger ion-dipole interact...
For water, Delta H_{vap} = 40.65 kJ mol^{-1}, and the normal boiling point is 373.15 K. Calculate the boiling point for water on the top of a mountain of height 5500 m, where the normal barometric pressure is 380 Torr. Calculate the boiling point of water at the top of...
Boiling and freezing points of pure substances are well-known and easily looked up. For instance, almost everyone knows that the freezing point of water is 0 degrees Celsius, and the boiling point of water is 100 degrees Celsius. Freezing and boiling points change when matter is dissolved into...
1. How much heat, in kilojoules, is evolved when a 3.70 kg sample of molten Cu freezes? The normal boiling point is 1357 K, and the heat of fusion is 13.05 kJ/mol. 2. How much heat must be absorbed at How many joules of heat are remov...
2. A pressure cooker is being used in a location where the air pressure outside the cooker is 12 PSI. If the cooker can double the outside air pressure, what will be the boiling point of the water inside the cooker? 218 degrees F ...
