The Separation Of Argon, A Uniform Dc Electric Field At Different Discharge Gaps And Cathode Potentials

* The battery applies a voltage to the plates, charging one plate positive and the other plate negative. Alpha particles constantly released by the americium knock electrons off of the atoms in the air, ionizing the oxygen and nitrogen atoms in the chamber. The positively-charged oxygen and nitrogen atoms are attracted to the negative plate and the electrons are attracted to the

Please Note: This lab involves a lot of waiting for the gas collection. Make sure you allot yourself the full three hours to perform the experiments.

- I think that the electrons that are emitted from the cathode are emitted with a range of velocities (perhaps like a Boltzmann distribution where average speed clusters in the middle of the range).

In the fourth stage of this experiment, the density of a gas was determined. A 250ml flask was weighed with an empty rubber balloon and the mass was recorded.

The Hindenburg disaster happened in 1937. The cause of the disaster was an electrostatic discharge which lead to igniting the hydrogen that was leaking. The ship before it crush had a major problems with hydrogen leaking. So until today the investigation show that the spark happened because of the difference of electric charge of the airship and the atmosphere which 60 meters about sea level to ignite fire in the ship. The ship didn’t last long in the air because it was filled with flammable gas.

AP Chemistry Mrs. Johnson Chemistry Butane and Inquiry Lab Submitted By Germaine Washington September 30, 2016 Abstract The purpose of these experiments was to determine the validity of the Ideal Gas Law. In the first experiment we used a Butane lighter to conduct a collection of C4H10 gas over water, with which we would measure the volume of the butane produced. It was found the 0.16 g of Butane gas at 299°K and 1.005 atm held a volume of 100mL. The results supported the Ideal Gas Law, PV = nRT.

Plasma is usually an ionized gas, meaning that one electron has been taken or added to an accumulation of atoms or molecules. This state of matter, which the founder called "radiant matter," was first identified in 1879 by Sir William Crookes inside a discharge tube. It was later renamed "plasma" by Irving

The purpose of this experiment is to investigate some physical and chemical properties of gases and to use these properties to identify these gases when they are encountered.

An anode is the negatively charged electrode that loses electrons and also where oxidation takes place.

In this experiment, we will collect data from the sample and use the Ideal Gas Law:

The Teltron Tel 2533 Critical potentials tube contained neon gas kept at fixed, low pressure. Within this tube were a collector ring and a diode electron gun. The filament was kept at a fixed current of 1.2A. Any current higher than this would have done serious damage to the filament. The diode electron gun was used to emit a beam of electrons from its cathode. This beam passed from the cathode through the neon gas present in the tube to the anode. The collector ring within the critical potentials tube was connected to a fixed power supply of 1.25V and a Levell TM8 pA-meter to record the collector current. The fixed power supply of 1.25V was so that the collector ring was made positive relative to the anode. A variable accelerating

The threshold frequency varies with each metal. When the sodium plate was exposed to high frequency light, electrons were emitted and were attracted to the positive terminal, causing a flow of current. However, when a low frequency light was used no electrons were emitted and therefore there was no current. Observations of the Photoelectric Effect 1. Current flows as soon as the negative terminal is illuminated.
