1. In the picture below, energy is being converted to heat water. What type of energy transformations take place in this model?

Suppose in an electric kettle there is water , when water is boiled the electrical energy changes into thermal energy when heating is done.
The thermal energy then gets transferred to the water . When the boiling takes place in the water the energy gets transformed into sound.
Lastly at the end the gravitational potential energy finally changes to the kinetic energy.

There are three types of energy transformations taking place

(i) conversion of kinetic energy to rotational energy

(ii) conversion of rotation energy to electrical energy

(iii) conversion of electrical energy to heat energy

As seen in the image attached, there is running water that is falling on the blades of a small turbine and makes it rotate. The turbine is connected to the heating system with wires.

Now, the energy transformations that take place in heating water are described as follows:

The flowing tap water is falling on the blades of the turbine which produces torque and makes the blade rotate. Hence, the kinetic energy of the tap water is converted into rotational energy.
Now the turbine is connected to the heating system with wire, which means it must produce electricity. Here, The rotation energy is converted into electrical energy.
Lastly, the electrical energy produced by the turbine is being converted into heat energy by the heating system to warm water.
