"Firm and stable in shape; not liquid or fluid."

Solid


1

"Dynamic quality."

Energy

1

"Conversion of a substance from the liquid or solid phase into the gaseous (vapour) phase."

Vaporization

1

"A substance that decreases the rate of, or prevents, a chemical reaction."

Inhibitor

1

"The process of measuring the amount of heat released or absorbed during a chemical reaction."

Calorimetry

5000

"A substance or matter in a state in which it will expand freely to fill the whole of a container, having no fixed shape (unlike a solid) and no fixed volume (unlike a liquid)."

Gas

5000

 "The energy that a piece of matter has because of its position or nature or because of the arrangement of parts. "

Potential Energy

5000

"The process of turning from liquid into vapor."

Evaporation

5000

"Any substance that increases the rate of a reaction without itself being consumed."

Catalyst

5000

"The minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport."

Activation Energy

5000

"A substance that flows freely but is of constant volume, having a consistency like that of water or oil."

Liquid

5000

"Energy which a body possesses by virtue of being in motion."

Kinetic Energy

5000
"The lowest temperature that is theoretically possible, at which the motion of particles that constitutes heat would be minimal. It is zero on the Kelvin scale, equivalent to –273.15°C or –459.67°F."


Absolute Zero

5000

"A substance that acts as a catalyst in living organisms."

Enzyme

5000

"A measure how much the energy of atoms and molecules become more spread out in a process."

Entropy

10000
"The temperature at which a given solid will melt."


Melting Point

10000
"The temperature at which a liquid turns into a solid when cooled."


Freezing Point

10000

"The speed at which a chemical reaction proceeds."

Reaction Rate

10000

"A state in which the rate of the forward reaction equals the rate of the backward reaction."

Chemical Equilibrium

10000

"Interrelation of heat and work with chemical reactions or with physical changes of state within the confines of the laws of thermodynamics."

Thermodynamics

5000000

"A unit of energy equivalent to the heat energy needed to raise the temperature of 1 gram of water by 1 °C (now often defined as equal to 4.1868 joules)."

Calorie

5000000

"A branch of science that deals with the effects of forces upon the motions of material bodies or with changes in a physical or chemical system."

Kinetics


5000000

"The SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves one meter in the direction of action of the force, equivalent to one 3600th of a watt-hour."


Joules

5000000

"The measurement of energy in a thermodynamic system."

Enthalpy

5000000

"Describes what happens to a system when something momentarily takes it away from equilibrium."
