How entropy relate to heat and temperature?
Entropy means disorderness in interatomic state. When heat is given, temp. rises and entropy increase as mobility in inner part increase. But when we cool down substance, entropy decrease as mobility slow down.
Does entropy increase or decrease due to friction?
Entropy is a measure of disorder. Heat is a very low order form of energy. Friction produces heat energy and hence entropy tends to increase due to friction.
How does the second law of thermodynamics relate to how energy is passed on through the food chain?
The second law of thermodynamics states that as more chemical reactions occur, more heat energy is released in to the atmosphere. Apparently, heat energy is useless and so as more energy is transformed into heat energy, more entropy (or instability in the overall universe) becomes prevalent. So as energy is being consumed and passed up the food chain, chemical reactions to digest the food occurs and , as a result, entropy increases.
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 the example of the statement the entropy of the universe can never decrease?
If a source of heat energy starts radiating from a point and continues without stop the entropy around that point will never decrease. As sun is the endless heat energy radiating source and surrounding's of that is known as universe accepted by everybody. So this is the example for the statement ' the entropy of the universe can never decrease.'
What is heat death how you can relate this term to entropy?
Heat death is a hypothetical situation in which there is no more usable energy in the Universe. In relation to entropy, it means that entropy is at its maximum - it can't increase any more.

How would you describe the change in the arrangement of particles as heat energy and temperature increase?
When heat is added, the arrangement of the particle (the Entropy of the system) will become more disorganized and Entropy will increase. When heat is taken away, the arrangement of the particles will become more organized and Entropy will decrease.

What is an increase in entropy?
In almost every process there is an increase in the entropy in the universe. For example, lets say your room is dirty so you think you are decreasing entropy by cleaning it up (decreasing disorder). The truth is that you expend a great amount of energy cleaning your room, and that energy is ultimately released into the universe as heat energy. That heat energy is a less ordered form of energy than the form you received it in, which are the chemical bonds in food. The chemical bonds in food are relatively ordered, but heat energy is very random. heat energy dissipates into the universe randomly, with little order or integrity. So you see, no process conserves all the energy in the process, as some energy is dissipated, or "wasted", as heat energy. When you hit a pool ball into another, the friction between the balls takes some of the energy of the collision away, in the form of friction. Friction generates heat (as you know from rubbing your hands togeter in the cold). I hope these brief examples demonstrate that all processes increase the entropy of the universe (in the form of heat energy).
Why does the engine not release all of the chemical energy as mechanical energy?
Because of the behavior of thermodynamics (entropy), it wastes some of the energy in the form of heat.

How do you use steam tables?
The steam tables have 16 columns as follows: pressure (absolute), temperature, specific volume of vapor, specific volume of liquid, heat of the liquid, heat of vaporization, total heat of the vapor, entropy of the liquid, entropy of vaporization, entropy of the vapor, internal heat of the liquid, internal heat of vaporization, and internal heat of the vapor (occasionally the external heat of the liquid, vaporization and vapor are included) If the temperature and pressure of steam are known then cross referencing the heat or the volume of a known quantity of the steam can be done. the heat content(enthalpy) of the liquid or vapor can be extrapolated from the chart, as can the entropy and internal energy. The enthalpy less the internal energy = the external energy (or the actual energy required to expand the liquid to a vapor) By determining the starting heat content of steam and final or exhaust heat content of steam the efficiency of a steam engine can be determined. Along with these calculations are the determinations of heat losses, steam quality, loss to entropy,...etc. all calculated using various instruments and the steam tables.
What form of energy is produced because of entropy?
thermal enegy..... ha ha i knew this and you did'nt cuz your stupid
How much energy to boil a hard boil egg?
Entropy is a thermodynamic term. Re the hard boiling of an egg: You are going to a more "ordered" state , i.e., positive entropy. However, entropy in this case is overwhelmed by the -∆H which is the negative heat provided by the proteins hydrogen bonding. Thus, the energy driving force is the important term and not the entropy in this case.
