physical properties of oxygen gas

A radioactive nucleus or element emits an alpha or a beta particle and gets converted into a new nucleus or element. The process of destruction of the original nucleus during the formation of new nucleus due to radioactivity is called Radioactive decay or disintegration. When a α - particl..

Velocity of Sound in Gases (Newton's Formula) - We know that the properties of a medium that govern the propagation of a mechanical wave are: a restoring force an inertial mass The restoring force acting on the particles of the medium is intimately connected to the approximate elastic mod..

It is a mixture of gaseous hydro-carbons. It is found usually along with petroleum deposits. Natural gas consists mainly of 85% methane, 10% of ethane and 3% of propane and butane. It may also contain nitrogen, oxygen, carbon di-oxide and hydrogen sulphid..

It is a mixture of gaseous hydro-carbons. It is found usually along with petroleum deposits. Natural gas consists mainly of 85% methane, 10% of ethane and 3% of propane and butane. It may also contain nitrogen, oxygen, carbon di-oxide and hydrogen sulphide. Its great advantage i..

. In chemical calculations, volumes are often expressed in litres (L) and pressures in atmospheres (atm) in this system, to four significant digits, We can express the ideal gas equation, equation (3), in terms of the mass m t o t of gas, using m t o t =nM fr..

At any temperature, the pressure of a gas depends upon its volume. If the volume is kept constant, the pressure depends upon the temperature and increases steadily with rising temperature. The constant volume gas thermometer uses the pressure at constant volume as the thermomet..

Helium - Neon Gas Laser - The figure shows the elements of a type of laser that is often found in student laboratories. The glass discharge tube is filled with a 80%-20% mixture of the inert gases helium and neon. Helium is the "pumping" medium and neon is the "lasing" medium. The above f..

Consider a sample of an ideal gas at pressure , volume V and temperature T. Let m be the mass of each molecule and v the rms speed of the molecules. Also, let v t r be the rms speed of the gas at the triple point 273.16K. Note : The international committee on weights and me..

1) No point can be at different potentials, so equipotential surface for different potentials can never touch or intersect. 2) Potential energy does not change as a test charge moves over an equipotential surface and hence the electric field can do no work on such a charge. Because of th..

Additivity - If a system consists of two point charges q 1 and q 2 , then the total charge of the system is got by adding q 1 and q 2 . Thus, the charge add up like real numbers (scalars). When we add charges, one should take care of its sig..
