Unformatted text preview: o In/dependent variables are different. ± Phase diagram: T=independent variable, P=dependent variable. ± Heating curve: Heat=independent variable, T=dependent variable. • As solid changes into liquid, point in phase diagram will not change but point in heat curve will. (A) incorrect because this is heating curve. (B) At 3 atm, CO 2 only has one phase change (Gas – Solid). Look phase diagram of CO2 above. This would have been a right answer if question was asking for a cooling curve at above the triple point. Therefore, (C) is right answer. heat energy removed heat energy removed heat energy removed...
