Brief Biographical Sketch:
My name is Abrahim. I go by Bimo. I'm a chemistry major at Stanford. Chemistry is fun! Past Classes(Clicking a class title will bring you to the course's section of the corresponding course catalog)S322: Why your room gets messy: the laws of thermodynamics in Splash! Spring 2009 (Apr. 04 - 05, 2009)
An introduction to the laws of themodynamics through three simple demonstrations and a story.
Demos:
1) Entropy: A drop of dye in a cup
2) Supercooling of a liquid: place a soda in a clear glass bottle in a freezer three hours prior. When it's removed it's not yet froze, but bang on a table and it freeses! Illustrates the concept of "activation" energy of phase transitions. It takes a small amount of energy to drive a phase transition.
3) What is temperature (Gas laws): What happens when you heat a ballon, what happens when you put it in the regrigerator??? Student will inflate balloons at the beginning of class and measure the circumference with a string before and after refrigeration at the end of the class.
4) Zeroth Law of thermo: what happens when when we mix a hot and cold liquid? take initial temperatures of both hot and cold water before and after mixing at different time points.
