Questions & Step-by-Step Solutions
Which of the following processes results in an increase in entropy?
Step 1: Understand what entropy is. Entropy is a measure of disorder or randomness in a system.
Step 2: Identify the process mentioned in the question, which is isobaric heating. Isobaric means the pressure remains constant.
Step 3: Recognize that during isobaric heating, the temperature of the gas increases.
Step 4: Note that as the temperature increases, the gas molecules move faster and spread out more.
Step 5: Understand that when gas molecules spread out and move more freely, the disorder in the system increases.
Step 6: Conclude that since the disorder (entropy) increases when the gas is heated at constant pressure, isobaric heating results in an increase in entropy.
