How does decreasing the temperature affect the volume of a gas?
The molecules will not collide as often with the walls decreasing the volume
Determine the volume of hexane that contains 5.33 X 10 22 molecules of hexane.?
11.6 is the volume of hexane that contains 5.33 X 10 22 molecules of hexane.
Why does gas have no specific volume?
gas has no specific volume because the molecules can be compressed or expanded, which would change the volume. like there is a smaller volume of gas in a can of soda then in the atmesphere around you.
If you put 4 milliliters of salt into 50 milliliters of water why does the volume not increase by the amount you put in?
It's because the salt disolves into the water instead of adding more volume to it. The salt molecules are "taken apart" (dissociated) by the water molecules, and they are converted into Na+ and Cl- ions. These ions can fit "between" the water molecules, and can do so without increasing the volume of the solution. More salt can be added without increasing the volume, too. That is until saturation is reached, and then no more salt will go into solution. Adding additional salt beyond this point will increase the volume.
How many ammonia molecules are in a mole of ammonia?
There are 6.02x10^23 molecules in one mole of anything.
Can the removing of energy increase the volume of a substance because the molecules come closer together?
No. It can increase the volume in some cases, but not BECAUSE the molecules come closer together. If the molecules come closer together, the volume will DECREASE.
Why a gas would have higher entropy than a liquid?
Gas molecules have fewer constraints on their location, than liquid molecules. Molecules in a liquid have to remain in contact with the other molecules of the liquid, and are limited to a specific volume. Gas molecules can go anywhere, they are not connected to anything. So with more possible locations, gas molecules represent a state of higher entropy or disorder.
Assumption of kinetic theory of gas?
The volume occupied by gas molecules is negligible when compared to volume occupied by the gas.The collisions between gas molecules-gas molecules and gas molecules-walls of the container are perfectly elastic.
What has mass volume and is made of atoms?
molecules
What three things affect airpressure?
Heat, number of molecules, atmospheric pressure and volume Volume * Pressure = molecules * molar gas constant * Heat
How is density related to the packing of molecules?
molecules are packed together and make volume density.
Why does the volume of a gas decrease when pressure increases?
As pressure increases, the molecules of the gas are compressed, reducing the amount of space between molecules, which results in a decreased volume.
What is mass and no of molecules of O2 having volume 22.4 dm3?
22,4 L is the molar volume. 1 mol of oxygen has 32 g and and 6,022140857.10e23 molecules.
Do gas have a definite volume yes or no?
No. A gas will fill any available volume by expanding and thereby reducing its pressure.Conversely, reducing the volume of a container of gas will increase the density of the molecules, which is increasing the pressure.No, one of the characteristics of a gas is that it does not have a definite volume but expands to fill its container.
Would it be possible to cool a real gas down to zero volume?
No. As a gas contracts you are only reducing the volume between the atoms/molecules. The atoms/molecules of a real gas have their own volume that does not change with temperature.
Does a paperweright have volume?
Yes. Everything has volume. Anything with 3 dimensions does, i.e. anything that exists
How does decreasing the temperature affect the volume of a gas?
The molecules will not collide as often with the walls decreasing the volume
