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 calculate with the combined gas law formula

2. To determine the absolute zero from a plot of pressure and temperature.
3. To Extrapolate a best fit line.

Period  7:

1) Classwork – Work on the Gas Law packet (page 1, and 2)  by using all of the variables (P,T, and V).

Period  8:

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

2) Lab 11 – Determine the experimental value of absolute value of Temperature in Kelvins.

Todays Lesson:

Gay- Lussac’s Law Demo: Temperature decreases the Pressure decreases – (direct proportion)

Bubble wrap and the Vacuum Chamber: Proof that atmospheric pressure is present. Take it away and there is less force pushing in the plastic bubbles of air and thus these air bubble expand till they pop.

Egg in and Out of the Bottle – Pressure and Temperature are a direct proportion

Egg in and Out of the Bottle – Pressure and Temperature are a direct proportion

11/20 –  Monday  “A” Day Homework:

1. Please complete the form below based on gas laws (from our demos and page 1, 2 of the gas law worksheet that we completed today and the completion of the Heat of Vaporization of liquid nitrogen (Lab 10).  You have three submissions!

1. COMPLETE LAST NIGHTS FORM IF YOU DID NOT KNOW I HAD A WEBSITE YET OR THERE WAS NO WIFII UNTIL YOU ENTERED MY CLASS TODAY!

Tryptophan is an essential amino acid:
It is found in all foods that have complete set of amino acids (that out body cannot make) !

Based on the above chart you can see that turkey does not have the greatest amount of proteins with tryptophan.

AND NO tryptophan does not make you sleepy!!!  If it did vegetarians would always be asleep because they love tofu which is made of soybeans!

Also if that myth was true turkey sandwiches would have warning labels like,

“Do not operate heavy machinery while digesting turkey!”

How many tryptophan related accidents would we have on Thanksgiving?

Acidic or Basic Foods:
