A measurement of the energy content of a system

When the forward rate of a chemical reaction is the same as the reverse rate. This only takes place in reversible reactions because these are the only type of reaction in which the forward and backward reactions can both take place.

A measurement of the randomness in a system

A biological molecule that catalyzes reactions in living creatures

It's the same thing as the Law of conservation of energy.

The amount of heat required to increase the temperature of one gram of a substance by one degree.

The temperature and pressure at which all three states of a substance can exist in equilibrium.

A change that occurs by itself.

When a compound combines with oxygen gas to form water, heat, and carbon dioxide

When the 3-D structure of a protein breaks down due to heat (or pH, etc), it's said to be denatured. This means that it unravels because the intermolecular forces between atoms in the chain aren't strong enough to hold it together anymore.

A chart which shows how the phase depends on various conditions of temperature and pressure.

The state of a compound (solid, liquid, or gas)

When you boil a liquid.

When a vapor reforms a liquid. This is what happens on your bathroom mirror when you take a shower.

It is a line graph that represents the change of phase of matter, typically from a gas to a solid or a liquid to a solid.

When a solid can change directly into a gas. Dry ice does this.

Phase change

It is the physical process by which a protein chain acquires its native 3-dimensional structure, a conformation that is usually biologically functional, in an expeditious and reproducible manner.

It is the thermodynamic property of a system that changes by an amount equal to the work done on the system when it suffers an adiabatic change. It is the sum of the kinetic and potential energies of its constituent atoms, molecules, etc.

The pressure of a substance that's present above it's liquid.
