A gas fills completely the vessel in which it is kept

Gas Filling in a Vessel Gas filling in a vessel refers to the process of filling a container with gas. The gas is stored in the vessel until it is needed for use. The process of gas filling is governed by certain principles of physics, including the laws of thermodynamics and the ideal gas law. Process of Gas Filling The following are the steps involved in the process of gas filling in a vessel: 1. Preparation of the Vessel The vessel must be clean and free of any contaminants before it can be filled with gas. This is to ensure that the gas remains pure and does not react with any foreign substances. 2. Selection of the Gas The type of gas to be filled in the vessel is selected based on its intended use. Different gases have different properties and are used for different purposes. 3. Calculation of Pressure and Volume The pressure and volume of the gas required for the vessel are calculated based on the size of the vessel, the type of gas, and the intended use of the gas. This is done using the ideal gas law. 4. Transfer of Gas The gas is then transferred from its storage container to the vessel using a filling hose. The pressure and volume of the gas are carefully controlled during this process to ensure that the vessel is filled to the correct level. 5. Sealing of the Vessel Once the vessel is filled with gas, it is sealed to prevent any gas from escaping. This is usually done using a valve or a stopper. Conclusion In summary, gas filling in a vessel is a process that r...

(d) The particles of air are very loosely bounded. They are far away from each other having a lot of space between them. Hence we can easily move our hands in the air. But in a solid block, the particles are tightly held by a strong force of attraction. So there is some or no space between them. Hence we need a karate expert.

(a) A gas fills completely the vessel in which it is kept. • Views: 5,804 ( 10 , 000 volts) was passed through the discharge tube under normal pressure of 1 atmosphere ( 760 mm ). No electricity could flow through air as it is a very poor conductor of electricity. (ii) The pressure inside the discharge tube was slowly reduced by the vacuum pump. On reducing it to about 1 mm oflmercury and on passing electric discharge again, electricity started flowing through the tube. As a result, light was emitted inside the tube. (iii) The emission of light stopped when the pressure inside the tube was further reduced to about 0.01 mm mercury. The walls of the discharge tube opposite to the cathode started glowing with a greenish light called fluorescence. At high voltage and low pressure the bonds between the molecules break down and the bonds between atoms also break down. Charged particles are separated out from it. On further investigations, it was found that the fluorescence is due to the bombardment of the walls of the tube by the rays emitted from the cathode. These were known as cathode rays. Thomson repeated the experiment by replacing air with a number of gases and by also changing the metal which constituted cathode, Gas Air at very Discharge tube ( 1 ike transparent glass) To vacuum Pump to flow ∝ High voltage Generator ( 10 , 000 vot Current Fig.2 Cathode ray experiment
