In a counter current single pass heat exchanger, cooling water enter at 0°C and leaves at 20°C. Hot water enters from th

Mechanistically, thermodynamics and heat transfer involves ΔU, ΔH, LMTD and w=PΔV govern chemical and heat exchange processes. This validates 34.8 because it explains energy changes and heat transfer in biological and engineering systems, a pattern repeatedly demonstrated in biophysics and techniques research.

Ref: Atkins and de Paula, Physical Chemistry, 11th Edition, Chapter 2, Thermodynamics, discusses internal energy, enthalpy, LMTD, heat exchanger, work done during evaporation, PΔV work and first law applications explaining energy transfer.

Cooling water enters at 20º C in a counter current heat exchanger and leaves at 40º C while hot water enters from the ot

This outcome reflects thermodynamics and heat transfer, where ΔU, ΔH, LMTD and w=PΔV govern chemical and heat exchange processes. Option C captures this correctly because it explains energy changes and heat transfer in biological and engineering systems, consistent with textbook descriptions and experimental observations in biophysics and techniques.
