Can entropy decrease during a process?
in general entropy will not decrease in a spontaneous process since spontaneous process are all irreversible ones. entropy can be reversed only through an reversible process by an ideal engine but it is impossible to create such an engine by violating second law of thermodynamics. hence entropy cannot be decreased practically
Entropy is the measure of the amount of disorder in a system?
true
Which has a greater torque a perpendicular force applied at the end of a wrench handle or an equal force applied in the same direction near the middle of the handle?
the perpendicular force applied at the end of a wrench handle. Because torque= Fd / T = F d cos θ therefore the greater the distance the greater the torque. T=torque F=force d=distance cos=cosine θ=theta
What is the larger of the two mating gears?
The gear with the greater number of teeth; it will have a lower angular velocity .
Is the resistance in the start winding greater or less than the resistance in the run winding?
The resistance in the start winding is greater because it is longer and thinner and has the greatest resistance to current flow
Describe the conditions necessary for a sample to have zero entropy?
The only way to have zero entropy is to have a temperature of absolute zero.
Is greater than the entropy of a liquid?
The entropy of a gas is typically greater than the entropy of a liquid due to the increased molecular randomness and freedom of movement in the gas phase compared to the more ordered structure of a liquid. The higher entropy of a gas reflects its greater number of possible microstates and therefore its increased disorderliness.
When will be entropy negative?
Entropy is a measure of disorder in a system and is always equal to or greater than zero according to the second law of thermodynamics. Entropy cannot be negative in a closed system.
What is the relationship between entropy and temperature?
The relationship between entropy and temperature is that as temperature increases, entropy also increases. This is because higher temperatures lead to greater molecular movement and disorder, which results in higher entropy.
What are the units of entropy and how do they relate to the measurement of disorder in a system?
The units of entropy are joules per kelvin (J/K). Entropy is a measure of disorder in a system, with higher entropy indicating greater disorder. The relationship between entropy and disorder is that as entropy increases, the disorder in a system also increases.
How does temperature affect entropy?
Temperature affects entropy by increasing it as temperature rises. This is because higher temperatures lead to greater molecular movement and disorder, which results in an increase in entropy.
Which of the following has greater entropy bromine vapor or liquid bromine Iodine vapor or solid iodine Justify your answer.?
Vapors always have more entropy than liquids of the same substance at the same temperature, because the number of energy states accessible to molecules in the vapor phase is much greater than in the liquid phase.
How does the entropy of the system change when the temperature of the system increases?
When the temperature of a system increases, the entropy of the system also increases. This is because higher temperatures lead to greater disorder and randomness in the system, which is a characteristic of higher entropy.
Is high entropy favorable in thermodynamics?
In thermodynamics, high entropy is generally favorable because it indicates a greater degree of disorder or randomness in a system. This increase in entropy often leads to more stable and balanced conditions.
What happens to the entropy of gas as it is heated?
As a gas is heated, its entropy generally increases. This is because the increased molecular motion and disorder associated with higher temperatures lead to a greater number of microstates available to the system, resulting in higher entropy.
How does the occurrence of exothermic reactions impact the entropy of the surroundings?
Exothermic reactions release heat energy to the surroundings, increasing their entropy by dispersing the energy. This leads to greater disorder and randomness in the surroundings, contributing to an overall increase in entropy.
What is the relationship between temperature and molar entropy in a chemical system?
The relationship between temperature and molar entropy in a chemical system is that as temperature increases, the molar entropy also increases. This is because higher temperatures lead to greater molecular motion and disorder, resulting in higher entropy.
