1. Water Apply Vaporization. Make sure that you are showing each step of your work. 1. How much energy is absorbed when 30.3 g of liquid water boils? 2. An energy unit often encountered is the calorie (4.18 J = 1 calorie). Determine the molar enthalpy of fusion of ice in calories per gram. 3. A typical ice cube has a volume of about 16.0 mL. Calculate the amount of energy needed to melt the ice cube. (Density of ice at 0.°C 0.917 g/mL; molar enthalpy of fusion of ice 6.009 kJ/mol;molar mass of H2O 18.02 g/mol.)

3. The Gas Laws Apply In this unit, you learned about Boyle’s law, Charles’s law, and Gay-Lussac’s law. Now, you will demonstrate your understanding of these concepts by creating a PowerPoint presentation which addresses the following prompts. You may use multiple slides for each question if needed. In part of your unit project, you will explain how to use Boyle’s law, Charles’s law, and Gay-Lussac’s law, so this activity is important to prepare you for your project. Make sure you explain each step as if you were teaching it to one of your classmates.

5. Diffusion and Effusion Apply In this unit, you learned about Graham’s law of effusion. Now, you will demonstrate your understanding of these concepts by responding to the following prompt. In part of your unit project, you will explain how to use Graham’s law of effusion, so this activity is important to prepare you for your project. Make sure you are showing each step of your work. If a molecule of neon gas travels at an average of 400 m/s at a given temperature, estimate the average speed of a molecule of butane gas, C4H10, at the same temperature. |
