Chemistry Honors – Class 44

Boiling

Dates

  • Periods B, D: Monday, November 24th
  • Period G: Tuesday, November 25th

Lab Submission

  • Questions?
  • Comments?
  • Uncertainties in the lab?
  • Note – there is no further lab work required. Make sure you have the Calculation section perfect…

Next Step

  • How can we extend this idea?
  • What would happen if we mix hot and cold water? Could we predict the result?

Activity

  • Predict the final temperature of a mixture of two cups of water.
  • 1st Cup = 125.0 mL @ 23.5°C
  • 2nd Cup = 182.3 mL @ 67.8°C
  • Constants: Dw = 1.01 g/mL, sw = 4.18 J/g°C
  • Hint – how is this related to the lab? how should I start BEFORE entering numbers?

Homework

  • Finish In-Class Problem by the next class
  • No (additional) HW over Thanksgiving Break
  • Note – for those wishing to get ahead, the next test will cover textbook sections 6.1, 6.2, 6.4 so you might take notes on those parts. We will (of course) cover these in class) but the next exam is the Friday after we get back.

Reminder

  • Any test corrections being submitted due by Tuesday @ Lunch
  • No points for test corrections alone – quiz Tuesday @ lunch
  • One problem – related to but different than test questions
