13. SpongeBob SquarePants 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 ). Flow rate equation R = V / t where R - flow rate, V - volume and t - time.
14. Two cities are known to be 34.8 km apart. Someone did an experiment that measured the distance between the two cities and determined the distance to be 47.6 km. What was the Percent error? Please write the Equation first. (you will not be able to do this by Dimensional Analysis).
15. _____________________________, ___________________ In the blank space, please write the heat equation and delta T equation.
16. How much heat (in kcals) is required to raise the temperature of 675ml of water from 35.6degC to 62.9degC?
17. What is the mass of olive oil if you added 5.1kJ to the oil (making some deep fried chicken, thanks for recipe Rachel Ray!!) and the oil's temperature raised from 63.2degC to 87.3degC? (coil = 1.97J/(g degC) ).
18. What is the specific heat of a substance if the temperature of the substance is raised from 15.2degC to 47..3degC by adding 14.1kcal of heat energy. The mass of the substance is 2.3 kg. Please put answer in cal / (g degC).
