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.
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.
Is it true In a rigid container when the speed of the gas molecules increases the speed of the gas also increases?
It is true that, in a rigid container, when the speed of the gas molecules increases, the temperature of the gas rises. This has nothing to do with the speed or lack of speed of the gas as a whole.
When a gas changes into a liquid it is called and the speed of the molecules is .?
condensation and the speed decreases
How many acetone molecules are in a bottle of acetone with a volume of 330 ml?
The number of acetone molecules is 24,843.10e23.
When high speed molecules mix and collide with slower speed molecules the high speed molecules do what?
Slow down and the temperature drops.
How does the speed of molecules of gas change when heated?
The speed of the molecules speeds up when the gas is heated.
How are molecules moving from vapor to liquid?
Molecules speed up when they are turned from liquid into vapor. This is because they have more freedom to move around due to gaseous properties. Gases conform to the volume of the container, so they have more room to spread out, compared to liquids that do not have the ability to change volume
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.
An indirect measurement of the speed of molecules is made with a?
An indirect measurement of the speed of molecules is made with a thermometer.
When a gas changes into a liquid it is called condensation and the speed of the molecules is increased or decreased?
the speed of the molecules decreases.
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
Does speed of sound have pitch or volume?
"speed" does not have pitch or volume. it is the distance covered over time.
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.
A measure of the speed of molecules is the?
particles
