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 does the 2nd Law of Thermodynamics say about Direction of heat transfer?
In nature heat only moves naturally from warmer systems to cooler systems. One direction only. Never naturally from something cold into something hot. We can pump heat out of a system by doing work on it, such as a refrigerator where the refrigerant is compressed - making it much hotter than the surroundings - then letting it give off heat to the surroundings, then expanding it across a valve where the evaporation and expansion causes it to get colder than the inside of the fridge - then allowing it to absorb heat from the inside of the fridge, then sending it back to the compressor to start all over again.
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.
Does organisms need energy?
Organisms use energy to divide, grow, remove wastes and to make protein. The organisms are able to do this by the process of the Krebs Cycle.
What is randomness or chaos in chemistry?
The amount of disorder/randomness of a system is called the entropy of the system.

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.
What is the Meaning of Entrophy?
Entropy is a measure of the disorder or randomness in a system. In thermodynamics, it is a state function that quantifies the amount of energy in a system that is unavailable to do work. As entropy increases, the amount of useful energy available decreases, leading to a more disordered state in the system.
Is it true that the entropy of a system decreases over time?
false
Which thermodynamic law has to do with entropy?
The second law of thermodynamics, generally stated, is that the entropy of an isolated system always increases in any natural process where change occurs. In a system at equilibrium, of course, the entropy remains constant.
What causes entropy to change when a solute dissolves in a solvent?
The solute becomes less ordered. (apex)
Can you decrease the entropy if yes then how and if not then why?
You cannot reduce entropy because entropy increases (Second Law of Thermodynamics), if you could, we could have perpetual motion. When work is achieved energy is lost to heat. The only way to decrease the entropy of a system is to increase the entropy of another system.
What statement best describes the second law of thermodynamics?
The entropy of the universe is increasing
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.
When does entropy increases?
Entropy increases when ever energy is used up. Energy cannot be destroyed, but it is always lost in the form of unusable energy. Entropy is the % of unusable energy compared to usable energy in a given system.
How does the entropy of the system change when equal volumes of ethanol and water are mixed to form a solution?
It increases
