ressure', Why is the slope different between phase 1 and phase 3? O the change in temperature was different between liquid water and solid water O the liquid water was heated at a different rate than solid water O liquid water has a different heat capacity than solid water O liquid water has a greater density than solid water

You may want to reference Section 3.7 (Pages 80-87) while completing this problem. Using the values for the heat of fusion, specific heat of water, and/or heat of vaporization, calculate the amount of heat energy in each of the following.

3. Calculate the heat required to increase the temperature of 630 grams of ice from -2℃ to 23℃ and turn it to steam with temperature of 124℃. The specific heat of ice is 2.108 J/(g∙℃).

A pure sample of Substance S is put into an evacuated flask. The flask is then heated steadily and the temperature measured as time passes. The results are graphed below, in the middle (in green). Identical experiments are now run on Substance Y and Substance Z. Substance Y is just like S except that it has a higher heat capacity in the solid phase C₂ (s). Substance Z is just like S except that it has a lower enthalpy of vaporization H. Select the graphs below, on the left and right, that show the results you expect for these new experiments. Substance Y •C₁ (s)) (higher Cp (Drag the slider to choose an image) temperature (°C) Substance S added heat (kJ/mol) Substance Z (lower H₂) (Drag the slider to choose an image) ³ 5

Under normal atmospheric pressure, nitrogen boils (and condenses) at -196oC. When 7.7 g of nitrogen gas at -196oC was put into a dewar flask initially at -260oC, their temperatures reach -210oC. The specific heat capacity and heat of vaporization of nitrogen are 1.04 J/g-oC and 200 J/g. Based on the system described above, is the following statement true or false? The nitrogen released heat and the flask absorbed it.

Heat does not have to be present in all phase changes. True O False
