Enthalpy is the transfer of energy (symbolized by delta H) Entropy is disorder and is symbolized by s or delta s, these two things together give you gibb's free energy, which allows you to determine whether a reaction will be spontaneous, and under what conditions.

Entropy: The state of disorder in a thermodynamic system: the more energy the higher the entropy. Enthalpy: The energy released or absorbed when a compound is formed from the elements in their standard states. Entropy is the energy in the system, whereas enthalpy is the energy released or absorbed when a reaction takes place.

Enthalpy is the heat content in a system. Entropy is the amount of disorder in a system.

They have different units for one.
dQ = T dS This equation tells us that the heat input to
"the system" is dQ. This is a change in energy or energy per unit mass. T is the temperature (absolute, e.g. Kelvin). dS is the change in entropy. So dS has units of energy/temp.
The physical meaning of entropy is that it is a measure of disorder in the system.
Enthalpy is one of many measures of the internal energy of the system (or internal energy per unit mass). (Other internal energies are Free energy and Gibbs Free energy.) The issue of the specific meaning of this internal energy is rather complex.

entropy is randomness in a system. enthalpy is the energy expended in a system. i think. ah, gimme a break, school was 7 years ago :) i'm pretty sure though.

entropy is heat absorbed in a reversible system and enthalpy includes the work done... not just the the internal heat
