What happens to the entropy of a system as more heat is added beyond the boiling point?

Fundamentally, if the entropy of a system increases, that means that the energy of the system ("normalized" to , i.e., divided by the temperature of the system) has become more "dispersed" or "dilute".
For instance, if a system increases its volume at constant energy and temperature, then the energy per unit temperature is now more "dilute", being spread over a larger volume.
All spontaneous processes result in a "dilution" or "spreading out" of the energy of the universe. The more dilute the energy of a system is (the higher the entropy of that system) the harder is is to harness that energy to do useful work.
Another useful way of thinking about entropy is to consider it as a measure of the amount of information needed to completely specify the state of a system. Ultimately, this means how much information is needed to specify the positions and momenta of every particle in the system.

∙ 11y agoAccording to the laws of thermodynamics, when temperature increases, entropy typically increases. The level of disorder (entropy) in a given system is usually proportional to the amount of energy in the system...though, this is not always the case.
If the temperature goes up (while G remains constant in a closed system), and entropy remains constant, the heat will go up proportionally to the increase in temperature.
d=Delta (means "the change in")
G=total free energy
T=temperature (measure of the speed of molecules)
S=entropy or disorder of a system (entropy always increases for a closed system says 2nd law of thermodynamics)
H=heat (energy necessesary to exert a force that accelerates a 1kg mass at 1m/s2 over a distance of 1m)
dG = TdS-dH
I think.
Increased temperature will decrease entropy.
As a general rule entropy - S - is a measure of disorder. As the temperature increases, the molecular motion also does as the particles are more energetic. This results in more randomness or disorder. So, yes, the entropy increases as the temperature increase.

What happens to entropy when pressure decreases?
When pressure decreases, entropy increases. Increases in entropy correspond to pressure decreases and other irreversible changes in a system. Entropy determines that thermal energy always flows spontaneously from regions of higher temperature to regions of lower temperature, in the form of heat.
What is randomness or chaos in chemistry?
The amount of disorder/randomness of a system is called the entropy of the system.
What does the second law of thermodynamic say about entropy?
The entropy of the universe is increasing
When salt is dissolved in water do you think the entropy of the system of salt and water increases or decreases?
Entropy will decrease.
What does entropy of a reaction describe?
The amount of randomness in the system
What happens to the entropy of gas as it is heated?
In a closed system the entropy is constant.
What is the measure of disorder and randomness?
Entropy is the measure of system randomness.
Is the tendency of a system to become more disordered?
Assuming this is a chemistry question... The entropy of the system increases, as entropy is considered a measure of randomness of a chemical system. The universe favors entropy increases.

The amount of decay or disorder in a system is called?
Entropy
How does the entropy of a system change for condensation of water?
The entropy is lower.
According to the second law of thermodynamics does entropy increase in a cold system?
That depends on what you mean by "cold" system. Entropy in any system can do one of three things: increase, decrease, or remain constant. If the system is closed, then entropy will only ever increase. If the system is open, entropy within it can do any of the three, provided there is a corresponding change in entropy outside the system (energy must come from or go to somewhere to effect an entropy change). The absolute amount of energy in the system makes no difference to the entropy of it. It is whether you have an open or closed system that counts.
What happens to the entropy of the cards when they are knocked over?
That depends on how you define "level of entropy". Usually the term refers to the degree of randomness in a system. If the system is defined as a deck of cards, then the level of entropy will depend on how randomized the cards are. A standard deck comes with the cards in a pre-set order for which the entropy would be considered zero (perfect order). Any deviation from that initial order would then increase the level of entropy; it is thus necessary to not only state what the system is (a deck of cards) but to also state the condition of the system (how well shuffled the cards are) before you can determine the level of entropy of the system.

The amount of disorder/randomness of a system is called the entropy of the system.
Is there anyway to decrease the entropy?
Only by increasing the entropy of another system.
When the entropy does not remains constant?
The entropy does not remains constant if the system is not isolated.
What is meant by entropy?
Entropy is a measure of the amount of disorder a system has. More accurately the amount of work that can be extracted from a system. The more entropy a system has the less work that can be done. 1kg of steam at 500 degrees can do lots more work than a kilo of warm water. Entropy always increases in a closed system. Entropy is why everything eventually breaks down.
