Questions & Step-by-Step Solutions
If 100 J of heat is added to a system at a constant temperature of 300 K, what is the change in entropy?
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.
Entropy Change Calculation – The question tests the understanding of how to calculate the change in entropy (ΔS) using the formula ΔS = Q/T, where Q is the heat added and T is the absolute temperature.
Thermodynamic Principles – It assesses knowledge of thermodynamic principles, particularly the relationship between heat transfer and entropy in a system at constant temperature.
