The addition of a small amount of ___________ to H2O may actually reduce friction compared to H2O alone.
The addition should be done on the order of 0.3% consistency although it can be higher at higher flow velocities, so it could actually reduce friction compared to H2O alone.
The elevation in the boiling point for 13.44 g of CuCl2 dissolved in 1Kg of water as solvent will be (Kb = 0.52 k kg mol-1 ; molar mass of CuCl2 = 134.4 g/mol )
Correct Answer :- c
Explanation : ΔTb = iKfm
ΔTb = [1000 × 0.52 × 13.44(1+2α)]/[134.4 × 1000]
ΔTb = 0.156 (∵α = 1)
