What is entrophy?

Entropy is:It is denoted by S.It is a state function and ΔS is independent of path.Entropy is a measure of the degree of randomness or disorder in a system.Greater the disorder of a system, the higher is the entropy. The decrease of regularity in structure means increase in entropy.Crystalline solid is the state of lowest entropy (most ordered) and the gaseous state is a state of highest entropy.As the temperature increases, randomness increases, and thus, entropy increases.For a reversible reaction, entropy change (ΔS)(for a reversible reaction)At equilibrium, ΔS = 0Entropy of a spontaneous reaction increases till it reaches the maximum, and at equilibrium, ΔS = 0Entropy is a state property. Therefore, entropy change for a reversible process is given byFor reversible and irreversible isothermal expansion of an ideal gas (that is under isothermal conditions), ΔU = 0. But is not zero for the irreversible process.Main definition are stated according to http://wiki.answers.com/Q/FAQ/8454.Thermodynamics is the study of energy conversion between heat and mechanical work which leads to the macroscopic properties such as temperature, volume, and...


As water is cooled its density does what until it reaches about 4 C?

As water is cooled its density increases until it reaches about 4 C and then it decreases.


What does force applied to a stationary object give the object?

Newton's First Law of Motion states that objects will remain in their current state of motion (whether stationary or travelling at a constant velocity) unless an outside force acts on them. If he force you are mentioning here causes the net force to become unbalanced, then the force will cause the object to accelerate until the forces are balanced and it reaches either a constant speed, or the opposing force causes it to decelerate and eventually become stationary.


What would a graph of a person being pushed by a constant unbalanced force look like?

Presumably this graph would register velocity vs. time. Presuming velocity on the y-axis and time on the x-axis, the graph would look like a half parabola. The person would accelerate infinitely. The key is that the force is "unbalanced." A person falling reaches equilibrium, ie. terminal velocity, when the upward force of wind resistance equals the downward force of gravity. Without some check to the acceleration, the person would accelerate faster and faster, forever.This is, of course, a purely hypothetical supposition. There is no such situation where this would occur. Even a person falling into a black hole would have a finite fall.


Liquid alcohol will change to vapor when its temperature reaches the what?

Liquid alcohol will change to vapor when its temperature reaches its boiling temperature. When alcohol reaches its boiling temperature, each molecule of alcohol has enough energy to separate from each other, so each molecule can move freely. The boiling point of liquid alcohol is 351K or 78C

What is ion product constant?

Ion product constant is essentially when something reaches equilibrium. Such as in the case of water. When water reaches its ion product constant it becomes both a base and an acid, reaching equilibrium.


When a chemical reaction and it and reverse are occurring at the same time and at the same rate the reaction has achieved?

equilibrium


What describes a reaction that reaches equilibrium?

The product and reactants reach a final, unchanging level.


When does a chemical reaction reaches equilibrium?

equilibrium means the rate of forward reaction = rate of backward reaction... there are three types of equilibrium 1. amount of products > amount of reactants 2. amount of products = amount of reactants 3. amount of products < amount of reactants


How does a system at equilibrium respond to the addition of more product?

Product added to a system at equilibrium will result in the reaction moving left, or using up product to make more reactants until it reaches equilibrium again.


When a chemical reaction and it's reverse occur at the same time and rate the reaction is said to be?

When the reaction reaches a point where reactants produced is equal to products produced the reaction is said to be in equilibrium. If that is what you afre talking about


Does all of the acetic acids dissociate after the reaction reaches equilibrium?

No. Acetic acid is a weak acid. It only partially dissociates.


What happens to the rate of enzyme concentration when you increase substrate concentration?

The rate of enzyme reaction is increased when the substrate concentration is also increased. However, when it reaches the maximum velocity of reaction, the reaction rate remains constant.
