A water wheel turning converts the potential energy of flowing water into mechanical energy, which can then be used to drive machinery or generate electricity.
The rushing water turning the blades of a water wheel is utilizing kinetic energy, which is the energy of motion. This kinetic energy is then converted into mechanical energy that can perform work.
The simplest example is water.

When thermal energy is transferred to water, the water molecules absorb the energy and their kinetic energy increases. This causes the temperature of the water to rise, eventually leading to the water boiling and turning into steam.
Water wheels or turbines turning generators.
Water itself is not energy, but it can contain and transfer energy. For example, water can hold thermal energy in the form of heat, kinetic energy in the form of waves or currents, and potential energy in the form of water stored in a reservoir.
Water turning into vapor is called evaporation. It occurs when heat energy from the surroundings is added to liquid water, causing the water molecules to gain enough energy to break free from the liquid phase and become water vapor in the air. This process is important for the water cycle and occurs naturally in bodies of water, like oceans, lakes, and rivers.
The scientific name for turning water into vapor is "water vaporization" or "water evaporation." This process involves the conversion of liquid water into water vapor through the addition of energy, typically in the form of heat.
An example of a solid to a liquid is ice melting into water.

The process of water vapor turning into liquid water is called condensation. This occurs when the water vapor loses heat energy and changes into liquid form. It is a key step in the water cycle.
