Question

Which description explains events that take place during the mixing? Select all that apply. Warm water molecules move more slowly than cold water molecules. Collisions result in transfer of energy from molecules of higher kinetic energy to molecules of lower kinetic energy. Warm water molecules slow down while cold water molecules speed up.

Answer 1

Collisions result in transfer of energy from molecules of higher kinetic energy to molecules of lower kinetic energy.

Warm water molecules slow down while cold water molecules speed up.

Explanation:

During the mixing of cold water and a hot water source, there is transfer of energy and at a point of equilibrium, both will be at the same temperature.

This is the point of thermal equilibrium.

• Here, the particles of the hot water have a greater amount of kinetic energy.
• They begin to collide with those of the cold water and transfer their energy to them.
• Due to the loss of energy, their molecules begins to slow down and the cold water molecules speeds up.
• With time, they will both have the same speed.
