Introduction The primary objective of this experiment is to determine the relationship between the pressure and volume of a confined gas. The gas we use will be air, and it will be confined in a syringe connected to a Gas Pressure Sensor. When the volume of the syringe is changed by moving the piston, a change occurs in the pressure exerted by the confined gas.
Information Specific to Liquid Oxygen General Oxygen is the second largest component of the atmosphere, comprising Liquid oxygen is pale blue and extremely cold. Although nonflammable, oxygen is a strong oxidizer. Oxygen is necessary to support life.
Oxygen will react with nearly all organic materials and metals usually forming an oxide. Materials that burn in air will burn more vigorously in oxygen. Equipment used in oxygen service must meet stringent cleaning requirements and systems must be constructed of materials that have high ignition temperatures and that are non-reactive with oxygen under the service conditions.
Vessels should be manufactured to American Society of Mechanical Engineers ASME codes and designed to withstand the process temperatures and pressures. Liquid oxygen is a cryogenic liquid. Liquid oxygen has a boiling point of Because the temperature difference between the product and the surrounding environment is substantial—even in the winter—keeping liquid oxygen insulated from the surrounding heat is essential.
The product also requires special equipment for handling and storage.
Oxygen is often stored as a liquid, although it is used primarily as a gas. Liquid storage is less bulky and less costly than the equivalent capacity of high-pressure gaseous storage. A typical storage system consists of a cryogenic storage tank, one or more vaporizers, a pressure control system, and all piping necessary for the fill, vaporization, and supply functions.
The cryogenic tank is constructed, in principle, like a thermos bottle. There is an inner vessel surrounded by an outer vessel. Between the vessels is an annular space that contains an insulating medium, from which all the air has been removed.
This space keeps heat away from the liquid oxygen held in the inner vessel. Vaporizers convert the liquid oxygen into a gaseous state.
A pressure control manifold then controls the gas pressure that is fed to the process or application. Vessels used in liquid oxygen service should be designed according to ASME codes for the pressure and temperatures involved.
Inhalation of pure oxygen at atmospheric pressure or less can cause pulmonary irritation and edema after 24 hours. Respiratory symptoms can occur in two to six hours at pressures above 1 atmosphere.
One of the earliest responses of the lung is accumulation of water in its interstitial spaces and within the pulmonary cells. This can cause reduced lung function, which is the earliest measurable sign of toxicity.
Other symptoms include fever, and sinus and eye irritation. When pure oxygen is inhaled at pressures greater than 2 or 3 atmospheres, a characteristic neurological syndrome can be observed.
Characteristic epileptic-like convulsions, which may be preceded by visual disturbances, such as loss of peripheral vision, also occur.
Continued exposure can cause severe convulsions that can lead to death. The effects are reversible after reduction of oxygen pressure.Boyle discovered the relationship between pressure and volume of gases that now bears his name.
This project shows you a simple method for re-creating this famous experiment. Objective. The goal of this project is to measure the relationship between the volume of a gas and its pressure, when the temperature of the gas is held constant.
When the volume of the syringe is changed by moving the piston, a change occurs in the pressure exerted by the confined gas.
This pressure change will be monitored using a Gas Pressure Sensor. It is assumed that temperature will be constant throughout the experiment. This pressure changes with temperature because at higher temperatures, the liquid has more energy, and likewise there is a greater probability of the gas escaping, and the escaped gas has more energy so it exerts a greater force on the.
Because if you increase the pressure of a gas, while keeping temperature the same, you increase the volume. Because if you decrease the temperature of a gas, while keeping pressure the same, you.
