Question 5 1 pts Entropy (Check all that apply) states that energy likes to disperse. states that it takes more energy to maintain an ordered state than a disordered state. explains why a sand castle won't spontaneously be built from a pile of sand. always increases in a closed system, according to the second law of thermodynamics. Question 6 1 pts Organisms will never run out of energy as long as the sun shines! because we can create energy. as long as the organism maintains a closed system. according to the first law of thermodynamics.

According to the third law of thermodynamics (abi 2.5) The entropy of a perfectly ordered, crystalline substance is zero at 0 Kelvin Exothermic processes decrease the entropy of the surroundings, at constant T and P The entropy of the universe increases for any spontaneous process The entropy increases for any spontaneous process Energy is conserved in any transformation of matter

The Second Law of Thermodynamics states that heat energy cannot transfer from a body at a lower temperature to a body at a higher temperature without the addition of energy. To assess the spontaneity of a process, we must use a thermodynamic quantity known as entropy (S). Entropy (S) is typically defined as the level of randomness (or disorder) of a system or a measure of energy dispersal of the molecules in the system. Increasing the volume of a substance increases the number of positions where each molecule could be, which increases the number of microstates. Therefore, any change that results in a higher temperature, more molecules, or a larger volume yields an increase in entropy. Here, the number of particles increases, so the entropy also increases.
Madhur L.
The entropy of the universe is constant, continually decreasing, continually increasing, or zero. It is not the same as the energy, E. The relationship between the entropy of a system and the number of different arrangements, W, in the system is given by S = klnW. At low temperatures, the reaction can become nonspontaneous if ΔH is positive and ΔS is negative.
