Define Entropy

explain and use the term entropy

Entropy can be best described as:Select one:a.The amount of energy available to do workb.The measure of disorder or randomness in a systemc.The total kinetic energy of particles in a systemd.The pressure exerted by a gas

Give mathematical expression forstatistical definition of entropy and statethe meaning of different terms involvedin it.

True or False:1. Entropy is a measure of the number of possible ways that the energy of a systemcan be distributed.2. The second law of thermodynamics states that entropy is always decreasing.3. Gaseous state of matter has the greatest motion and least orderly arrangement.4. The internal energy is often called chemical energy because it is the result of all themotion of the particles and the forces between them.5. For a given chemical reaction, if there is no work done on or by the reaction, thenthere must be a change in volume.6. Entropy is a statistical measure of heat of a system.7. If a chemical reaction is spontaneous, the total entropy of the chemical system andits surroundings increases only if the reaction is endothermic.8. The preferred direction in nature is toward maximum entropy.9. The two forces that drive chemical change are enthalpy and entropy.10. If ΔS is calculated to be positive, there is greater disorder in the products, whichwould drive the reaction in the forward direction.

What is entropy?A.Entropy is a measure of heat content.B.Entropy is a measure of energy in molecules.C.Entropy is a measure of randomness.D.Entropy is a measure of ability to do work.
