End of Spring 2007!

“The semester, she has ended”!

I just completed my last exam on Physics, and this marks the end of my semester. I hope to be more consistent in blogging my next semester here… Until then…

Chapter 20 begins here…

Filed under: PHY 106, Spring 2007 — Hamman @ 1:34 pm

We start off chapter 20 on the kinetic theory of gases. Today, we derived an expression for the root-mean square velocity of gas molecules wrt temperature, molar mass, and the Boltzman’s constant.

Root-mean square velocity

Then we derived an expression for the average kinetic energy of a gas solely in terms of the Boltzman constant and temperature, thereby proving that “temperature is a measure of the average kinetic energy of gas molecules”

Reading assignments were for 20.7 to 20.10

Transfer of heat :: Best lecture

Filed under: PHY 106, Spring 2007 — Hamman @ 8:10 am

Last Friday, we had what I would rate as probably the most interesting lecture I have had in all my courses. And I can say that because I can still remember the conversations we had on heat, how low temperatures affect us, how heat is transferred, and some very practical talks on all of this. Generally, heat is not one of my favorite topics, but this lecture was just super! Dr. Jeff often “digresses”, and we even talked about relativity! I loved this lecture!

Work processes

Filed under: PHY 106, Spring 2007 — Hamman @ 4:17 pm

We got into details of the processes involved in work done by a gas…

  • Isobaric – Constant pressure
  • Isovolumetric – Constant volume
  • Isothermal – Constant temperature
  • Adiatic – No addition of heat
  • Free expansion – No changes in internal energy, no addition of heat
  • Cyclic – Change in temperature is zero

Heat reservoirs and isometrics

Filed under: PHY 106, Spring 2007 — Hamman @ 1:24 pm

We learnt about heat and cold reservoirs. The main topic was the derivation of the formula for work done by a gas. Plus we touched on the Ideal gas equation, and some different isometrics involved in the gas equation.

  • Isobaric
  • Isovolumetric
  • Isothermal
  • Adiatic
  • Free expansion
  • Cyclic

We also learnt about a new kind of differentiation coming from path-dependant quantities, that would be different from path-independant ones.

Practical on work-energy postponed

Filed under: PHY 106, Spring 2007 — Hamman @ 2:21 pm

Well, we did go to the lab, but we won’t yet be doing away with the previous chapters’ lab. But no worries, we shall have thermal experiments yet!

Thermodynamics begins here

Filed under: PHY 106, Spring 2007 — Hamman @ 4:38 pm

We have entered a new chapter on heat and thermodynamics. Today, we learnt about temperature scales, methods of heat transfer, and some calorimetry. As usual, the class was great fun! Plus we got back our first exam results!

Tour de France in Physics!

Filed under: PHY 106, Spring 2007 — Hamman @ 12:02 pm

We had a very interesting lecture on energy conservation yesterday using the Tour de France cyclists as an example of how energy losses and gains are balanced out!

Dr. Jeff’s back!

Filed under: PHY 106, Spring 2007 — Hamman @ 3:35 pm

We had lectures today. Dr. Jeff Collier kindly came despite his recent illness. We had some solutions to difficult problems from the course text.

No class, sadly

Filed under: PHY 106, Spring 2007 — Hamman @ 2:35 pm

Dr. Jeff Collier has come down with malaria, so the practical session today did not hold. Here’s praying he gets well soon. The test to be held tomorrow is shifted to next week, so more time to study.
