Is Entrophy change in a system that undergoes a spontaneous process positive negative or zero?
Negative entropy is a process or chemical reaction proceeds spontaneously in the forward direction.Positive entropy is a process proceeds spontaneously in reverse.
What step in the rm process is focused on determining the probability and severity of s hazard occurring?
The step in the risk management (RM) process focused on determining the probability and severity of a hazard occurring is called risk assessment. This involves identifying potential hazards, analyzing their likelihood of occurrence, and evaluating the potential impact or consequences if they do occur. By assessing both the probability and severity, organizations can prioritize risks and develop appropriate mitigation strategies.
Why is experimental probability called experimental probability?
Because it is the process of deriving probability through repeated experiments.
What is the intersection of the assessed probability and severity of a hazzard in the CRM process?
what step in the composite risk management process is focused on detemining the probability and severity of a hazard occuring
What is mathematical definition of random process?
Probability model
What must happen to the entropy of the universe during a spontaneous reaction or process?
The entropy of the universe must increase during a spontaneous reaction or process. This is in accordance with the Second Law of Thermodynamics, which states that the total entropy of an isolated system can never decrease over time.
Which thermodynamic law has to do with entropy?
The second law of thermodynamics is closely related to entropy, stating that the total entropy of an isolated system can never decrease over time. This law provides a direction for natural processes, indicating that systems tend to move towards higher entropy states.
How does entropy change in an adiabatic process?
In an adiabatic process, entropy remains constant.
The tendency in nature for systems to become less ordered or organized is called what?
The tendency in nature for systems to become less ordered or organized is called entropy. This concept is central to the second law of thermodynamics, which states that in any natural process, the total entropy of an isolated system will always increase over time.
Process where entropy remains the same?
A process where entropy remains the same is an isentropic process. In an isentropic process, there is no net change in the entropy of the system. This typically occurs when there is no heat transfer and the system is adiabatic and reversible.
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
Does the entropy of the universe increase when a system undergoes a reversible process?
Yes, the entropy of the universe increases when a system undergoes a reversible process.
Is an increase in entropy of a system sufficient to make a process spontaneous?
Yes, an increase in entropy of a system is sufficient to make a process spontaneous.
When does an irreversible process occurs?
An irreversible process occurs whenever there is an increase in entropy. Entropy can be thought of as a measure of "wasted" energy, that is, energy that cannot be converted to useful work. Therefore any process which results in an increase in entropy wastes some portion of energy that cannot be recovered, and so the process is irreversible.
When is the change in entropy zero?
The change in entropy is zero when a process is reversible, meaning that the system and surroundings return to their original state without any net change in entropy.
Is Entrophy change in a system that undergoes a spontaneous process positive negative or zero?
Negative entropy is a process or chemical reaction proceeds spontaneously in the forward direction.Positive entropy is a process proceeds spontaneously in reverse.
What statement best describes the second law of thermodynamics?
The entropy of the universe is increasing
