Both the pouring process and the lack of heat source once the liquid is in the cups would cause it to lose heat, which translates to energy.
therefore the adverage kinetic energy is reduced
Average is not a relative term in your question, second law of thermodynamics is an expression of the universal law of increasing entropy, stating that the entropy of an isolated system which is not in equilibrium will tend to increase over time, approaching a maximum value at equilibrium.
In English, warmer body releases heat to cooler body, kettle is the warmer body and the molecular energy for each species are greater than the energy of the same spices after pouring them in the cup (which is the cooler body).
average kinetic energy is temperature.
so when you pour hot water into a cup, it cools down. the temperature goes down, therefore the average kinetic energy goes down.
