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.
According 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.
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.
Entropy increases.
It evaporates
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.
The amount of disorder/randomness of a system is called the entropy of the system.
The entropy of the universe is increasing
Entropy will decrease.
The amount of randomness in the system
In a closed system the entropy is constant.
Entropy is the measure of system randomness.
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.

Entropy
The entropy is lower.
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.
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.
Only by increasing the entropy of another system.
The entropy does not remains constant if the system is not isolated.
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.
