ANS:C - Δt^5/4

In the free convection regime of pool boiling, the heat flux (q) is proportional to the temperature difference between the surface of the heated object and the surrounding fluid (ΔT) raised to a power. This relationship is typically represented as: q∝(ΔT)n The exponent (n) depends on the specific conditions of the system. In the free convection regime of pool boiling, where buoyancy forces dominate and natural convection occurs, the heat flux is commonly found to be proportional to the temperature difference raised to the power of 5445​, as represented by: q∝(ΔT)5/4 So, the correct option is: ΔT5/4.
