Q: If 100 J of heat is added to a system at a constant temperature of 300 K, what is the change in entropy?
Solution:
The change in entropy ΔS = Q/T = 100 J / 300 K = 0.33 J/K.
Steps: 5
Show Steps
Step 1: Identify the amount of heat added to the system, which is 100 J.
Step 2: Identify the constant temperature of the system, which is 300 K.
Step 3: Use the formula for change in entropy, which is ΔS = Q/T.
Step 4: Substitute the values into the formula: ΔS = 100 J / 300 K.
Step 5: Calculate the result: 100 J divided by 300 K equals 0.33 J/K.
