According to the second law of thermodynamics does entropy increase in a cold system?
Yes, according to the second law of thermodynamics, entropy tends to increase in a closed system. In a cold system, if the temperature is below the surroundings, the heat can flow from the surroundings to the system, increasing the system's entropy.
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.
Which is a statement of the second law of thermodynamics?
Entropy tends to increase in a system.
What statements incorrectly describes entropy?
"Entropy decreases in a closed system over time." "Entropy only applies to physical systems, not chemical or biological systems." "Entropy is a measure of disorder, not the amount of energy in a system." "Entropy can be negative, indicating a more ordered state."
What remains constant in an isolated system?
An isolated system is one in which no external forces act. answer2. Energy and mass remains constant in an isolated system.

Is there anyway to decrease the entropy?
Only by increasing the entropy of another system.
What is the 2nd Law of Thermodynamics and Entropy?
Usable energy is inevitably used for productivity, growth and repair. In the process, usable energy is converted into unusable energy. Thus, usable energy is irretrievably lost in the form of unusable energy.
Is it possible for entropy to be negative and For entropy change to be negative and For entropy production to be negative?
Assuming you mean can entropy be reduced; the answer is yes. Only in an open system such as our planet. The universe is a closed systems. The entropy of the universe cannot be reduced. Chemical changes can reduced entropy in an open system. When gas turns into a liquid or when a liquid turns into a solid; entropy is reduced.
What happens to the entropy of the cards when they are knocked over?
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.
Questions in thermodynamics with answers?
What is the first law of thermodynamics? The first law of thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another. What is entropy? Entropy is a measure of the disorder or randomness in a system. In thermodynamics, entropy tends to increase in isolated systems over time. What is the difference between heat and temperature? Heat is the energy transferred between two objects due to a temperature difference, while temperature is a measure of the average kinetic energy of the particles in a substance.
What statements incorrectly describes entropy?
"Entropy decreases in a closed system over time." "Entropy only applies to physical systems, not chemical or biological systems." "Entropy is a measure of disorder, not the amount of energy in a system." "Entropy can be negative, indicating a more ordered state."
Does entropy depend on its path?
No, entropy is a state function, which means it depends only on the initial and final states of a system and not the path taken to reach those states.
What is special about the entropy in thermodynamic equilibrium compared to all statesof a system?
In thermodynamic equilibrium, the system's entropy is maximized, reaching a state of maximum disorder or randomness. This is unique compared to other states of the system where entropy may be increasing or decreasing as the system approaches equilibrium. At equilibrium, the system has reached a stable condition where the distribution of energy and molecules is uniform, making it a distinct state in terms of entropy.
How does the second law of thermodynamics contradict the philosophy of evolution?
!1. Evolution is a fact and the theory of evolution by natural selection explains much of this fact.2. The second law of thermodynamics is not violated by evolutionary theory as the second law only applies to closed systems and the earth is not a closed system. Ask any creationist to name the other laws of thermodynamics and get a blank stare for an answer.
