Gas Law Woorksheet
When scientists began to realize the relationship between the pressure, temperature and volume of a sample gas could be obtained which would hold true for all gases. Then they developed Gas Law. Here you can find some questions related to gas law and their answers: Questions: 1. At what temperature in the celsius scale, V (volume) of a certain mass of gas at will be doubled keeping the pressure constant? (a) (b) (c) (d) 2. 120 g of an ideal gas of molecular weight is confined to a volume of 20 L at 400 K. Using...

There are three states of matter, Solid, Liquid and Gas.The matter in gaseous state has relatively low density compared to solid state and has great expansion and contraction which changes pressure and temperature. In this article you can find some questions related to Gas and their states along with their answers: Questions: 1. The rate at which a gas diffuses at constant temperature: (a) Inversely as its density (b) Directly as the square of its density (c) Inversely as the square root of its density (d) Varies directly...

Van der Waals equation was derived by Johannes Diderik van der Walls in late 1873. He received Nobel prize in 1910 for his work on the equation of state for gases and liquids. Van der Walls equation relates pressure, volume and the temperature of a gas taking the finite size of molecules and their intermolecular attraction. In this article you can find some questions related to Van der Wall’s equation and their answers: Questions: 1. The correct expression for the van der Waa1’s equation Of states is: (a) (b) (c) ...

Liquefication of gas is the process of converting gas into a liquid state. This process includes a number of phases and it is used for scientific, commercial and industrial purpose. Liquefaction can also be used for finding the fundamental properties of gas molecules. In this article you can find some questions related to Liquefication of gas and their answers: Questions: 1. Collision frequency (Z) of a gas at a particular pressure: (a) decreases with the increase of temperature (b) increases with increase of temperature (c) ...
read moreWorksheet on Kinetic Theory of Gases
According to Kinetic theory of gas,” A gas is a large number of particles, which are in continous motion.” Kinetic theory helps to understand the macroscopic properties of gases which includes pressure, volume and temperature. In this article you can find some questions related to Kinetic Theory of gas and their answers: Questions: 1. Which of the following is not the postulate of thekinetic theory of gases? (a) Gas molecules are in a permanent state of random motion (b) Pressure of gas is due to molecular impact on the...

There are three states of matter. I.e Solid, Liquid and Gas. Gas is one of the classical state of matter. The word “gas” was first used by Flemish chemist, J.b Van Helmont in early 17th century. The gaseous state of matter can be found between the liquid and plasma state. Here you can find some questions related to gas, Boyle’s and Charle’s law along with their answers: Questions: 1. Which of the following statements is not correct about the states of matter? (a) Molecules of solids are least energetic (b) ...
