temperature of a gas is summartzed in Charles’law. This law states: at constant pressure‚ the volume of a particular sample of gas is directly proportional to the absolute temperature. Charles’ law may be expressed mathematically: V ". T (constant pressure) V = kT o‚ : T = k (constant pressure) (1) (2) where V is volume‚ T is Kelvin temperature‚ and k is a proportionality constant. dependent on the number of moles and the pressure of the gas.

Newton’s Second Law Lab Preliminary Questions 1. When you push on an object‚ the magnitude of the force on the object directly affects it’s motion. If you push harder on the object‚ it’s motion is larger. 2. If we have a bowling ball‚ and a baseball each suspended from a different rope‚ and hit each ball with a full swing of a baseball bat‚ the ball that will have the greatest amount of change in it’s motion will be the baseball. This is true because the baseball has a smaller mass than a bowling

is employed to express quantitatively the ideal gas model. Postulates: 1- A gas consists of molecules of mass (m) and diameter (d). 2- Molecules move continuously and randomly. 3- Molecules are treated as points‚ having no volume 4- Molecules collide with each other‚ changing direction and velocity. 5- Collisions are elastic (no loss of translational energy) no potential energy of interaction between them.

Coulomb’s Law 1. Objective - To study the validity of Coulomb’s law on a simple electroscope. This will be split into two parts; first measuring the the force as a function of distance‚ and second we will look at how the magnitude and sign of the charges affect the force. 2. Theory- As is well known‚ like charges repel and opposite charges attract. That being said‚ the strength of those forces also depends on the distance between the two charges
