Entropy: Heat addition to surrounding.

In summary, the entropy change of the surroundings is 40.272 kJ/K due to the loss of 12007 kJ of heat at an ambient temperature of 25 degrees centigrade.

If 12007 kJ of heat is lost to the surroundings with an ambient temperature of 25 degrees centigrade during a cooling process, and the ambient temperature of the surroundings is unaffected by the heat addition, what is the entropy change of the surroundings?

If Δs=∫δQ/T, then Δs=ΔQ/T=12007 kJ/(25+273.15)K= 40.272 kJ/K.

Is my thinking process here correct?

Thanks!

Yes.
 

1. What is entropy?

Entropy is a measure of the disorder or randomness in a system. It is a thermodynamic property that describes the amount of energy in a system that is unavailable for work.

2. How does heat addition affect entropy?

When heat is added to a system, it increases the randomness of the molecules and therefore increases the entropy. This is because the molecules have more energy and can move around more freely, increasing the disorder in the system.

3. Why is entropy important in thermodynamics?

Entropy is important in thermodynamics because it helps us understand the direction of energy flow in a system. In any process, the total entropy of the universe always increases, meaning that energy tends to disperse and become more evenly distributed.

4. Can entropy be reversed?

The second law of thermodynamics states that entropy cannot be reversed in an isolated system. This means that in a closed system, entropy will always increase or stay the same. However, in an open system, entropy can decrease locally, as long as the total entropy of the universe increases.

5. How is entropy related to the concept of disorder?

Entropy and disorder are closely related because entropy measures the level of disorder in a system. As entropy increases, disorder increases, and vice versa. This is why entropy is sometimes described as a measure of the randomness or chaos in a system.
