Answer the following showing all work and/or in a clear and concise manner.<br> <br> <br> 1. What is the difference between temperature and heat?<br> <br> <br> <br> <br> 2. What is the definition of activation energy (E<sub>ac</sub>)? <br> <br> <br> <br> <br> 3. Potential energy of the reactant (PE<sub>r</sub>) is _________ compared to the potential energy of the product (PE<sub>p</sub>).in an exothermic rxn.<br> <br> 4. ___________________ is a substance that is currently a gas but at room temperature is a liquid.<br> <br> <br> 5. State the 2nd law of thermo and then explain via the Kinetic Molecular Theory (<nowiki>KMT</nowiki>).<br> <br> <br> <br> <br> <Br> <br> <br> 6. Absolute zero is the condition where __________________________. The condition of absolute zero is _________________ and _________________.<br> <br> <br> 7. Entropy is the measurement of _______________________________<br> <br> <br> 8. If a system (for example water) has a delta H that is "-", the system (i.e. water) would be releasing or absorbing energy/heat? Circle correct answer.<br> <br> <br> <br> 9. What does not change through a phase change ______________________?<br> <br> <br> 10. What are the two units of energy that you know and what is the conversion factor between them.<br> <br> <Br> <br> <br> <br> <br> <br> 11. Explain the difference between a Relative temperature scale (i.e. Celsius) and Absolute temperature scale (i.e. Fahrenheit). <br> <br> <Br> <br> <Br> <br> <br> <br> <br> <br> <br> <Br> <br> <br> 12. <nowiki>SpongeBob SquarePants</nowiki> wanted to go on a diet and he lost 4.2E3 mL/hr of water. If he was on the diet for 2.56 days, how many gallons of water did he lose? (1 gal = 3.785 L ). <br> <br> <br> <br> <br> <br> <br> <br> <Br> <br>
