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. Keep in mind that the sign of the heat involved in the state change is ignored. 3 E D C R F 5 T ▬▬▬ B FO 6 Q Search H ▼ Part A FZ ▼ N Copyright © 2023 Pearson Education Inc.

The heat of fusion is equal to the heat of solidification. 73°F Partly sunny O True O Search L CHO False & 09

How much heat is required to warm 25.0 g of H2O from a solid at -12ºC to a liquid at 60ºC? ∆Hfus = 6.02 kJ/mol Csolid = 2.09 J/gºC Cliq = 4.18 J/gºC Tfreezing = 0ºC

Calculate the amount of heat needed to raise the temperature of 55.0 g of liquid water from 25°C to 99°C. The specific heat of liquid water is 1.00 cal/g °C

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
