• Gas Law Experiment

NTRODUCTION In this experiment the validity of Gas Laws were observed and the relationship of two variables, temperature and volume, against pressure was tested. Gas Laws are encompassed by the Ideal Gas Law in which PV=nRT observes the general behavior of a gas under ideal conditions in terms of pressure(P), volume(V), moles of gas(n), gas constant(R), and temperature(T). The Ideal Gas Law is a combination of Boyle 's Law, Charles ' Law and Avogadro 's Law and was first introduced in 1834 by Emile Clapeyron. For the purposes of this experiment, attention is given to Boyle 's Law and Guy-Lussac 's Law. British scientist Robert Boyle discovered the relationship between volume and pressure by using a J-tube and observing the volume that the gas…

• The Ideal Gas Law

The Ideal Gas Law relates several variables of state of an ideal gas with the following equation: P V = n R T, where P is the pressure of the gas in atmospheres, V is the volume of the gas in liters, n is moles of the gas, and T is the temperature of the gas in Kelvin degrees. R is the ideal gas constant. The Ideal Gas Law is a combined summary of Boyle’s Law, Charles’s Law, and the Avogadro’s Law. This Law works best under low pressure, room temperature (298K) environments because these…

• The Ideal Gas Law, Boyle's Law

Gases, solids, and liquids are the three states that a substance can exist as. A gas does not maintain shape and volume. Gases expand to fit and fill the container. While a liquid maintains volume, but not shape and fits the shape of the container it is placed in. Solids can maintain both volume and shape. When a gas exerts force on the walls of a container, this is known as its pressure. Pressure varies based on temperature and volume. Many gas laws were used within this experiment, such as…

• Ideal Gas Law Experiment

A flask will be filled to its max capacity and then filled with that gas. After that, the ideal gas law will be used to find mm (the molecular mass of a substance). The equation will be changed to mm=gRT/PV instead of the usual PV=nRT. There are several gas laws exhibited in this experiment. Dalton’s Law of Partial Pressures allows us to determine the pressure of the gas by subtracting the water vapor pressure from the total pressure of the flask. The total pressure would be the barometric…

• Aerosol Gas Laws

Aerosol cans and gas laws Global issue- During World War II the U.S government supported an investigation into finding a portable way for service men to spray malaria carrying bugs. Finding cure for malaria was a massive issue all over the world during World War 2 but when the cure was found the only possible way to prevent the disease from spreading was by killing the malarial bugs through spraying them. Getting a portable can to spray them was a huge problem during the World War 2 era as there…

• Molar Volume Of Gas Lab Report

Molar Volume of a Gas Lab The purpose of the lab was to do an experiment to determine the molar volume of hydrogen gas at standard temperature and pressure, or STP. To start the experiment, a beaker was filled with water and then a cage was created with a copper wire. A piece of magnesium was cut and placed inside the cage in order to keep the reaction going until all of the magnesium reacted with the hydrochloric acid. The eudiometer tube was filled with 15 mL of hydrochloric acid and water…

• Lab Report: Moolar Volume Of A Gas At STP

Formal Lab Report: Molar Volume of a Gas at STP Abstract: The purpose of this experiment is to find out how to experimentally determine what the volume of a mole of H₂(g) is at STP by using gas laws. The hypothesis for the experiment is that if H₂(g) is produced at RT and STP, Avogadro’s law can be used to experimentally determine the amount of H₂(g) because equal gases at the same pressure and temperature have the same amount of particles. In order to find the molar volume, hydrogen gas…

• Stp Lab

one mole of H_(2(g)) at STP. In a way, the problem is essential in understanding how one mole of an ideal gas at STP is always equivalent to 22.4 L. By determining if the volume of a mole of H_(2(g)) is 22.4 L, it supports Avogadro’s law that one mole of an ideal gas occupies 22.4 L at STP. At the same time, it indicates that a direct relationship exists between volume and the number of moles of gas as temperature and pressure stays constant. One real world application of the importance of this…

• Volatile Liquids Lab Report

Volatile liquids require a small amount of thermal energy to vaporize due to the fact that many contain nonpolar molecules. This property of volatile liquids was utilized in this experiment to determine the molar masses of unknown volatile liquids by employing the ideal gas law in the course of vaporization and condensation of the liquids. This was done by taking measurements of volume, temperature, mass, and pressure throughout various steps of the experiement. These findings were then applied…

• Latent Heat Of Nitrogen Lab Report

nitrogen and measuring how long it took for a fixed amount of nitrogen gas to be produced gave the rate of evolution of nitrogen gas. Plotting the power against the rate of evolution and determining the gradient yielded the value of 188 ± 22 kJkg¯¹ for the latent heat of vaporisation of nitrogen. This is within the accepted value of 199 kJkg¯¹ [1] but the uncertainty is very large which could have been minimised…
