HOMEWORK Description

PHYS 204 Week 6 iLab 8

  1. How long does it take for a thermometer to reach the same temperature as that of its surroundings?
  2. If I want my coffee to be as warm as possible, should I add the milk immediately upon pouring the cup or wait until I am ready to drink it?
  3. Paste a copy of your final temperature–time graph for the cooling thermometer here.
  4. What are the parameters of the natural exponent fit for the thermometer cooled in air?
  5. From the exponential fit, what is the time constant of the thermometer cooled in air?
  6. What are the parameters of the natural exponent fit for the thermometer cooled in water?
  7. From the exponential fit, what is the time constant of the thermometer cooled in water?
  8. Paste a copy of your final temperature–time graph for Part 2 here.
  9. What are the final temperatures for the two runs in Part 2?

Questions

  1. How long should I wait to be sure that the thermometer temperature is the same as the room temperature in air?
  2. Would I have to wait as long if I placed the hot thermometer in room temperature water? How long would it be?
  3. What should you conclude about adding milk to your coffee based on the results of Part 2?
