Who passed the Gas?

Today in class we learned about gases and how they act under different conditions. We also went over our tests and got our grades back of which everyone did wonderful on.

We learned 3 different characteristics of Atoms regarding atom speed:

1. As temperature increases, the speed of the gas atoms rises.

2. Lighter atoms move faster than heavier ones

3. All of the different atoms of a type will not move at the same speed, despite of being at the same temperature.

We then moved on to Pressure. Gases are always creating pressure. We measure this preasure in Psi; pounds per square inch. This means that by saying our atmosphere has a pressure of 15 psi, 15 lb's of pressure are being applied to us at all times. Psi can be found by the equation P= force / Area where force would be in lb's and area in square inches. So now we need to know where force comes from, we find two things; the amount of collisions of which the atoms have and the speed of which the atoms go when they collide

Their are a few different things that effects how much pressure is given by a set of atoms. All of the above Things listed for speed of Atoms, Temperature and type of atoms, effect the force of atoms given off because they increase both the amount of collisions and the speed at which they're colliding. Another effect to this is the space that the atoms are confined to; atoms with little room will collide more often.

That about wraps it up for the characteristics that we learned about atoms today. If you weren't at school then you should do the chemthink, behaviour of gases tutorial and questions. Otherwise, the Homework tonight is the webassign: measurements on Gases. The next scribe is Artie B.
