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 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…

last location will be in my bedroom on the top floor with the heat on. This is for the hot environment. The temperature will be at about 100° Fahrenheit. By doing this I will find out in which environment gases expand and contract the most in. The questions I researched were, how does temperature affect gas molecules, how does kinetic energy affect temperature change, and what is the Ideal Gas Law? Matter comes in four different forms, called states: solids, liquids, gases, and plasmas. In this…

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…

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 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…

In the winter, our gas got disconnected until the fall when the winter gas law had it turn it back on. My sister and I spent a lot of time at my Grandma’s house, because we couldn’t dry our clothes in a dryer and there wasn’t hot water for showers. My parents would heat water in a giant slow cooker we had that is similar to an oven, but can boil water fast and uses electricity instead of gas. This last summer, my mom got her job back for a while so we could keep up with the gas bill. In the…

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…

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…

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…
