Understanding Entropy

What is the relationship between the size of a box and the entropy of gas molecules within it?

• Larger boxes have less entropy

• Smaller boxes have more entropy

• Size of the box does not affect entropy

• Larger boxes have more entropy

How does the addition of heat to a clean room affect its entropy?

• It decreases the entropy

• It increases the entropy

• It has no effect on the entropy

• It makes the room cleaner

What is the easiest definition of entropy according to the lecture?

• The amount of disorder in a system

• The heat energy moving between mediums

• The total energy in a system

• The temperature of a system

Why is the energy released during the breaking of chemical bonds considered unavailable?

• It can be reused

• It decreases the system's entropy

• It increases the system's order

• It cannot be utilized

What is the formula for calculating entropy?

• S = Q + T

• S = T / Q

• S = Q * T

• S = Q / T

What happens to the entropy of a system when it loses heat?

• Entropy remains constant

• Entropy decreases

• Entropy increases

• Entropy becomes zero

In a system where heat is gained, what happens to the entropy?

• It remains unchanged

• It decreases

• It increases

• It becomes zero

What is the change in entropy of the universe during an adiabatic process?

• Always positive

• Always negative

• Always zero

• Always increasing

How does the entropy of the universe behave in a reversible process?

• It increases

• It remains constant

• It fluctuates

• It decreases

What is the general rule for the entropy of the universe?

• It always decreases

• It always fluctuates

• It always increases or remains constant

• It always remains constant
