You have probably seen the heating curve of water. This graph represents a cooling curve of another substance. You can see that over time, the temperature of the substance decreases and the substance changes from a gas to a liquid to a solid. What other information do we know about this substance as it changes?

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
