Document Summary
The behavior of water under pressure is an example of le chatelier"s. Principle at solid/liquid equilibrium, raising p squeezes the solid. It responds by going to phase with greater density, i. e. , the liquid phase. In any system, if you increase p the density will go up. Therefore as p goes up, equilibrium favors phase with the larger density (or smaller volume/gram. Changes of state are examples of phase changes, or phase transitions. Any of the three forms of matter (gas, liquid, solid) is converted to either of the other two. Heating curve a plot of temperature versus time where heat is added. As heat is added, the temperature of the ice increases linearly with time. Slope of the line depends on both the mass of the ice and the specific heat of ice, the number of joules required to raise the temperature of 1 g of ice by 1 c.
