When an amount of heat is transferred at a steady temperature, what happens to the entropy of the system gaining the heat?
a.It decreases.
b.It increases.
c.It is lost to its surroundings. >>>
d.It is unchanged.
To determine what happens to the entropy of the system gaining heat when an amount of heat is transferred at a steady temperature, we can look at the definition of entropy. Entropy is a measure of the disorder or randomness of a system.
When heat is transferred at a steady temperature, it means that the temperature of the system remains constant. In this scenario, the entropy of the system gaining heat would increase.
The increase in entropy occurs because when heat is transferred, the energy increases the number of microstates (possible arrangements of particles) that the system can occupy. As a result, the system becomes more disordered or random, leading to an increase in entropy.
Therefore, the correct answer is:
b. It increases.
