Why does water have an entropy of zero when it is at zero kelvin?
At absolute zero temperature, water molecules have no thermal energy to move or vibrate, leading to a highly ordered and structured arrangement. This low energy and high level of order result in minimal entropy, as entropy is a measure of the disorder or randomness in a system.
Which is not apt to increase entropy?
A perfectly ordered crystal at absolute zero is not apt to increase entropy, as entropy tends to increase with higher temperatures and disorder.
When will be entropy negative?
Entropy is a measure of disorder in a system and is always equal to or greater than zero according to the second law of thermodynamics. Entropy cannot be negative in a closed system.
What is the relationship between the change in entropy at constant volume and the thermodynamic property of a system?
The change in entropy at constant volume is related to the thermodynamic property of a system because entropy is a measure of the disorder or randomness of a system. When there is a change in entropy at constant volume, it indicates a change in the system's internal energy and the distribution of energy within the system. This change in entropy can provide insights into the system's behavior and its thermodynamic properties.
How can one calculate the change in entropy in physics?
In physics, the change in entropy can be calculated using the formula S Q/T, where S represents the change in entropy, Q is the heat transferred, and T is the temperature in Kelvin.
When does the change in entropy equal zero?
The change in entropy equals zero when a process is reversible, meaning that the system and surroundings return to their original state without any net change in entropy.
When a system is at equilibrium what is delta S?
At equilibrium, the change in entropy (ΔS) of the system is zero. This means that the system is in a state of maximum entropy where there is no further tendency for change in the system.
Describe the conditions necessary for a sample to have zero entropy?
The only way to have zero entropy is to have a temperature of absolute zero.
Are all reversible processes is entropic?
Yes. Isentropic means "constant entropy." For all reversible processes, the change in entropy for the system and its environment is zero.
How does the volume change in an isentropic process?
The entropy of an ideal gas during an isothermal process may change because normally the entropy is a net zero. The change of on isothermal process can produce positive energy.
When entropy is less than zero the probability of occurrence of such a process in an isolated system is?
I don't think entropy can get less than zero
How does the entropy change in the reaction 2c3h6g 9o2g 6co2g 6h2og?
The entropy change in a reaction can be calculated by comparing the entropy of the products to the entropy of the reactants. Without specific entropy values provided, it is difficult to determine the exact change. However, in general, the entropy change is positive in reactions where the products have higher entropy than the reactants, indicating an increase in disorder.
Is Entrophy change in a system that undergoes a spontaneous process positive negative or zero?
Negative entropy is a process or chemical reaction proceeds spontaneously in the forward direction.Positive entropy is a process proceeds spontaneously in reverse.
Is it possible for entropy to be negative and For entropy change to be negative and For entropy production to be negative?
Assuming you mean can entropy be reduced; the answer is yes. Only in an open system such as our planet. The universe is a closed systems. The entropy of the universe cannot be reduced. Chemical changes can reduced entropy in an open system. When gas turns into a liquid or when a liquid turns into a solid; entropy is reduced.

What is the third law of thermodynamics as defined by Ludwig Boltzmann?
"As a system approaches absolute zero, all processes cease and the entropy of the system approaches a minimum value.""it is impossible by any procedure, no matter how idealised, to reduce any system to the absolute zero of temperature in a finite number of operations".Lewis (of Lewis acids and bases fame) and Merle Randall phrased it as"If the entropy of each element in some (perfect) crystalline state be taken as zero at the absolute zero of temperature, every substance has a finite positive entropy; but at the absolute zero of temperature the entropy may become zero, and does so become in the case of perfect crystalline substances."
