Gases Flashcards
Gas molecules have no definite ___ or ___, are widely ___ and can be easily ____. They are in ___, constant motion
size, shape, separated, compressed, random
Atoms which exist in pairs due to unstable nature, and high reaction as a single atom
diatomic gases
Temperature is the measure of __ __ or movement of gas particles. Movement increase the ____ and, thus when collisions occurs, there is more energy or ___ transfer.
kinetic movement, velocity, heat
Gases do not have distinct ___, instead they take up the shape of the container.
volume
pressure is the ___ of the gas particles colliding with the __ of the container. An increase in _____ results in a decrease in pressure
force, colliding, area
When gas is confined to a container, an external force can compress that gas, and the volume ____. This results in more ____, and thus more ____.
decrease, collision, pressure
When the gas is expanded, the volume is ___, __ collisions, and __ pressure
increased, decreased, decreased
Expansion and compression of gasses is easy because there is a lot of ___ between the particles
space

An ideal gas behaves in __, __ and ___ motion, according to the kinetic molecular theory of gases
constant, random, straight-line
The kinetic molecular theory gasses states that particles in a gas are in constant, ____ motion, the combined __ of the particles is negligible, the particles exert no ___ on one another, the gas molecule collisions are completely ___, meaning there are no ___ ___ between the gases, and all gases have the same __ ___ __ at a given temperature.
random, volume, forces, elastic, intermolecular forces, average kinetic energy
