Kinetic energy
What is the energy an object has because of its motion.
100
the conversion of a liquid to a gas or vapor.
What is vaporization?
100
• Definite shape and volume • Almost incompressible • Expand only slightly when heat
What are solids?
100
results from the force exerted by gas per unit surface area of an object.
What is gas pressure?
100
The average kinetic energy of the individual particles in a substance.
What is temperature?
200
Kinetic theory
What is the theory that states that all matter consists of tiny particles that are in constant motion?
200
when conversion occurs at the surface of a liquid that is not boiling.
What is evaporation?
200
When heat is released
What is exothermic?
200
• Indefinite shape • Indefinite volume • Can be compressed
What is gas?
200
Solid, liquid, and gas, are states of matter changed by...
What is heat?
300
Gas pressure
What is the force that results from the force exerted by gas per unit surface area of an object?
300
It has indefinite shape, definite volume, almost incomprehensible, and expands only slightly when heat is applied.
What are liquids?
300
When heat is absorbed
What is endothermic?
300
Which state of matter has the most amount of kinetic energy
What is gas?
300
The kelvin temperature of a substance is directionally proportional to the average kinetic energy of the particles of the substance.
how is the kelvin temperature of a substance related to the average kinetic energy of its particles?
400
An empty space with no particles and no pressure.
What is a vacuum in science?
400
The boiling point is the temperature at which the vapor pressure of the liquid is just equal to the12 external pressure on the liquid.where as Normal Boiling Point—defined as the boiling point of a liquid at a pressure of 101.3 Pa.13
What is the difference between boiling point and normal boiling point?
400
the change of a substance from a solid to a vapor without passing through the liquid state.
What is sublimation?
400
• O KELVIN • Never produced in a lab • Coldest recorded boomerang nebula =1K
What is absolute zero?
500
the collisions of atoms and molecules in air with objects.
What is atmospheric pressure
500
A measure of the force exerted by a gas above a liquid.
What is vapor pressure?
500
have high melting points because relatively strong forces hold them together.
What are ionic solids?
500
In what state do molecules move extremely quickly and by bouncing off each other
What is a gas?
500
