Temperature and volume of asample of 2.00 mol of nitrogen decrease from Ti=400 K and Vi= 20 L to Tf = 200 K and V = 10 L. Calculate entropy changesfor gas (ΔSgas).
Expert Solution
Step 1
Given:
Initial temperature Ti=400 K
Initial Volume Vi= 20 L
Final temperature Tf = 200 K
Final Volume Vf = 10 L
Specific heat capacity at constant volume(Cv) of N2 = 20.7 J/mol.K
Step 2
Change in entropy is given by,
