Answer the following questions in a clear and concise manner.<br> <br> <br> 1. Was what you performed in this lab a physical (base particle did not rearrange) or chemical change (did rearrange). <br> <br> <br> 2. Was what you performed in the lab exothermic or endothermic. Explain<br> <br> <br> <br> 2. what is NOT changing when a substance goes through a phase change like melting? What is the energy being used for?<br> <br> <br> <br> <br> <Br> <br> 3. Why can not liquid particles go anywhere?<br> <br> <br> <br> <br> <br> 4. What is updated definition of boiling?<br> <br> <br> <br> <br> <br> <br> 5. What is the difference between a gas and a vapor?<br> <br> <br> <br> <br> <br> <br> 6. What are the two things that make evaporation different from boiling?<br> <br> <br> <br> <br> <br> <br> <br> 7. How is the actual heating curve different from the one most books show?<br> <br> <br> <br> <br> <br> <br> 8. Is phase changes or not phase changes (staying in same phase) require more energy, circle one.<br> <br> <br> <br> 9. What are the two things that are held constant (that most people don't talk about) when one is showing/explaining the heating curve?<br> <br> <br> <br> <br> <br> 10. In the space below or on the back of page, draw the actual heating curve (as we did in the lab in class) labeling axes.<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br>
