Molecules
A _____is composed of two or more atoms. All matter is made up of tiny and discrete particles, which cannot be taken apart without changing the chemical composition and identity of the substance. These particles are called _____
Diffusion
The process by which particles move freely to fill up any available space is called _____ ( ____ of gasses can be demonstrated by placing a jar of air over a jar).
Solids density
gasses have much lower densities because of the large space between gas molecules.
Gas density
The density of a ____changes with temperature and pressure. _____ density is usually measured in grams per liter (g/L).
Kinetic molecular theory
According to this theory, gases are made up of tiny particles that are always in random and straight line motion. These particles move very fast and can only change direction when they collide with one another or with the walls of the container.
Volume
___ Gases do not have a definite shape or volume. They expand to completely fill their container. The _____ of a gas placed inside a 1.5
Temperature
The average kinetic energy of gas particles of a given amount of gas is directly proportional to its absolute _____. The common units for ____ are degrees Celsius (0C) and degrees Fahrenheit (0F). The standard unit for _____ and the unit that will be used in providing a quantitative relationship with other properties of gases is the kelvin (K).
amount of gas
The _____ pertains to the amount of particles present in a given sample. The _____ is simply the mass of the given gas. However, it is very hard and impractical to measure the_______ .Instead, you will express the______ in terms of mole (n).
Pressure
The kinetic molecular theory describes ____ as the cumulative force that all the gases particles exert as a result of their collision with one another or with the walls of the container. _____ is simply the force exerted on a given area. (eto yung ineexert nila kapag yung mga tiny particles ay nagbubungguan)
Atmospheric pressure
The pressure exerted by the atmosphere on anything on Earth's surface is called ___
Barometer
is the instrument used to measure atmospheric pressure, was invented by Evangelista Torricelli.
Evangelista Torricelli
invented this simple barometer which is used to measure atmospheric pressure.

The kinetic energy of the particles is directly proportional to their absolute temperature
As the sealed, inflexible container is heated, the gas molecules inside____________.
The particles of gas are in constant motion and move in straight lines
Which postulate of KMT explains why the scent of fresh coffee in the morning fills up every room in the house?
Gases do not have fixed volume
Why are gases compressible?
the collision between the gas particles
