Explain why ice, which is a crystalline solid, has a melting temperature of 0 掳C, whereas butter, which is an amorphous solid, softens over a range of temperatures.
Consider a cylinder containing a mixture of liquid carbon dioxide in equilibrium with gaseous carbon dioxide at an initial pressure of \({\rm{65}}\) atm and a temperature of \({\rm{2}}{{\rm{0}}^{\rm{o}}}{\rm{C}}\). Sketch a plot depicting the change in the cylinder pressure with time as gaseous carbon dioxide is released at constant temperature.
