How much should the pressure be increased in order to decrease the volume of a gas by 10% at constant temperature?
In order to increase the volume of a gas by 10% , the pressure of the gas should be. Thus , if the volume is increased by 10% , the pressure should decreases by 10%. Thus , pressure is decrease by 10%.
How much should the pressure of the gas be increased?
∴ The pressure should be increased by 5.26% in order to decrease the volume of a gas by 5% at a constant temperature.
When a gas is filled in a closed vessel?
One more important thing is that students should observe the statement carefully. The vessel is closed. It means that gas cannot exchange matter with the surrounding. Hence moles constant and unless given, for a vessel, the volume of gas is also constant.
What is the compressibility factor equation?
Compressibility factor, usually defined as Z = pV/RT, is unity for an ideal gas.
Under which conditions of temperature and pressure density of a gas will be maximum?
At higher pressure and lower temperature, density of the gas will be the highest. Step-by-step answer: Density of any particular gas is related to pressure and temperature by the following equation.
Under which condition density of gas is maximum?
Therefore, to achieve maximum density we must have maximum value of pressure and lower value of temperature. Hence, option B is the correct option as it correctly represents the conditions for maximum density which is higher pressure and lower temperature. The correct answer is 273K and 2atm.
When the density of gas is maximum?
The density of gases depends upon the temperature. The higher the temperature, the more the molecules are spread out and the lower the density. The result is that warm gases rise and cool gases sink.
At which condition density becomes maximum a/p 0.5 atm and T 600 K B P 2 atm and T 150k c/p 1 atm and T 500 K’d p 1.5 atm and T 400 K?
Explanation: An ideal gas will have maximum density at high pressure and low temperature i.e. when P = 2 atm, T = 150 K.
What is the unit of gas constant?

What is the density of nitrogen monoxide gas at STP?
1.34 g/L
How do you find density at STP?
A. Density of a gas at STP. The formula D= M/V is used at STP with M being equal to the molar mass and V being molar volume of a gas (22.4 liter/mole).
How do you find the mass of a gas sample?
First the ideal gas law will be used to solve for the moles of unknown gas (n). Then the mass of the gas divided by the moles will give the molar mass. Step 2: Solve. Now divide g by mol to get the molar mass.
What is the relationship between mass and volume of a gas at STP?
The volume of 1 mole of any gas is called its molar volume and is equal to 22.4 L at standard temperature and pressure. Molar volume allows conversions to be made between moles and volume of gases at STP. Gas density can be calculated from the molar mass and molar volume.
