Beaker A: 15 C

Beaker B: 37 C

Beaker B contains water molecules that have the greater kinetic energy (on average).

Since beaker B is at a higher temperature than beaker A, the water molecules must be moving faster in beaker B than in beaker A (on average).

If heat is being applied to the beakers, then the increased amount of heat applied to beaker B is greater, and the heat will cause the water molecules in beaker B to move faster than the water molecules in beaker A (on average).

Kinetic energy = (1/2) (mass) (velocity)^2

Since the velocity of the a water molecule in beaker B is on average greater than the velocity of an average water molecule in beaker A, the water in beaker B has a higher kinetic energy.

The volume of the water in Beaker X will be 100cm3, as you are not adding any more water to the equation (50X+100Y is not 150Y or X, but 50X+100Y) The total volume of matter in Beaker X will be 150cm3, and if the beaker is labelled, the volume measure will indicate 150cm3 due to the displacement of water. But as the answer to your question, the volume of water in Beaker X must be 100cm3 even though visual indicators will not show this due to the displacement of water by marbles

beaker B because the oil is thicker therefore it will take more time to heat.
