A teacher sets up two identical beakers of water in science class.

The teacher heats both beakers. She adds more energy to beaker X than to beaker Y by heating it for a longer time.

Which statement is true about the the water particles in the two beakers after they are heated?
A.
There is no way to determine the average kinetic energy of the water particles.
B.
The water particles in beaker X and beaker Y will have the same average kinetic energy.
C.
The water particles in beaker X will have a higher average kinetic energy than those in beaker Y.
D.
The water particles in beaker Y will have a higher average kinetic energy than those in beaker X.

The correct statement is:

C. The water particles in beaker X will have a higher average kinetic energy than those in beaker Y.

This is because beaker X has been heated for a longer time, which means it has absorbed more energy. The average kinetic energy of the water particles is directly related to the temperature of the water; therefore, the water particles in beaker X will have a higher average kinetic energy compared to those in beaker Y.
