## Q2: week 3 – 11/27 – 12/1

” The first day of class should connect to the last day and every day in between!”

Please check Power School for accuracy!

Everyone needs to join Remind for class.  Click me to sign up.

I WILL NOT ACCEPT HOMEWORK AFTER 5:00 am the following day.  IF THERE IS A Problem YOU NEED TO EMAIL ME. IF YOU DO NOT and you do not complete your homework on time YOU WILL EARN A ZERO!

LAB 9  is LATE!!

Main focus:

1. To Complete Lab 10 – heat of vaporization of liquid nitrogen.

2. To Solve Combined gas Law problems
3. To determine the absolute Temperature in Celsius.

Period  6:

Cold Open: Crush the paint thinner can

1. Complete the Regents questions worksheet.

Period  7:

1) Lab 10 – heat of vaporization of Liquid Nitrogen – complete

– Used the virtual lab below to collect data for those that missed the data or the Lab.
– Reviewed IMF’s, vapor pressure, boiling points, and heat of vaporization.

Liquid Nitrogen notes:

N2(l) facts:     boiling point/condensation point =  -196ºC, 77 K, – 320 F

heat of vaporization = 199 J/g 199 J/g

If Liquid Nitrogen was placed on table H we would need a table this wide!!!

Red line = nitrogen,  Blue line = oxygen.
