The Nature of Gases
The device used to measure atmospheric pressure.
What is a Barometer?
The force exerted above the surface of a liquid by a gas.
The two types of solid forms?
What are crystalline solids and amorphous solids?
Dry ice, a substance that undergoes a direct change from a solid to a gas is an example of...
What is sublimation?
The constant movement of tiny particles is called ?
What is Kinetic energy ?
An area of no gas pressure.
What is a Vacuum
The conversion of a liquid to a gas.
What is Vaporization?
A translucent product that is formed by the binding of inorganic substances that have cooled to a firm state without being crystalized.
What is glass?
Describes when all three states or phases are able to co-exist in equilibrium.
What is triple point?
Happens to particles when the temperature reaches absolute zero.
What is the ceasing of kinetic movement/energy?
The way of movement displayed by the particles within a gas.
What is Rapid/Random?
The temperature where vapor pressure of the liquid is equal to the external pressure on the liquid causing the liquid to vaporize at an accelerated rate.
What is Boiling Point?
What do these few following elements have in common?
Carbon, phosphorus, sulfur, oxygen, boron, and antimony.
What are they all have allotropes?
What is one way you can show the relationship among the three states (solid, liquid, gas) of a substance in a tight container?
What is a phrase diagram?
The relationship between the kelvin temperature of a substance and the average kinetic energy of the particles in the substance is...
What is directly proportional?
How many pascals (Pa) are equivalent to 1 standard atmosphere pressure (atm)
What is 101.3kPa or 101,325 pascals
Reduces the amount of space between the particles in liquids.
What is Intermolecular Attraction?
These two temperatures are when a solid transforms to liquid or when a liquid transforms to a solid. They are the complete opposite of each other but when applied to a substance they are the same temperature.
What are melting point and freezing point?
What is the effect in the decrease in vapor pressures (less than 101.3kpa) ?
What is lowers the boiling point and raises the melting point.
The total amount of energy in a substance regardless of physical state or temperature.
What is Average Kinetic Energy?
Kinetic energy is transferred from one particle to another without loosing any of the total kinetic energy.
What is Elastic Collision
A state when the number of particles vaporizing is equal to the number of particles condensing.
What is Dynamic Equilibrium?
Solids that have strong forces keeping them together causing them to have a high melting point.
Example: Sodium chloride
What are Ionic Solids?
When vapor pressures surpass atmospheric pressure or near room temperature this happens when...
What is when sublimation occurs?
The characteristic giving particles the ability to leave the container they are being held in by overcoming the attraction/forces containing them.
What is Minimum Kinetic Energy?
