Lessons 5 and 6!

Today we covered two lessons. I will start with lesson 5, something important to know about Celsius scale and Kalvin is that on the Celsius scale, the temperature at which the volume of a gas is theoretically equal to 0 is 273 degrees Celsius. K= C+ 273 and C= K- 273. We also went into a little bit about absolute zero, which is the lowest a temperature can go. Temperature of 0k is = to absolute zero. The main thing we took notes on is Kinetic theory of gases! Here are some important things to know about it:

-gas particles are constantly moving

- motion is completely random

-speed is not always the same

- particles move in straight lines

- they have a lot of space to move

- they change direction when they hit each other or walls

-temperature increases so does speed

Lesson 6! We began to go over Charles's law which states that volume is proportional to the kelvin temperature. Also the proportionality constant, K, indicates how much the volume of gas changes per kelvin. Also, something important to know is that hot air rises because it is less dense than cooler air. Lastly! As temperature increases, volume of a gas increases and the density of the gas decreases. This is why warmer air rises above cooler air. We did cover some math problems figuring out new volumes when you convert it from c to K. The most important thing to know is that C= K-273 and K=C+273.
