2. hydropower
engine with large blades
3. renewable
use of water to generate electricity
4. turbine
organic material made from plants and animals

Explanation:

1) Biomass.

Organic material made from plants and animals.

Biomass materials are made up of plants or animals. They are used to generate the electricity. They have stored chemical energy. When bomass are burned they produces heat.

Some common examples includes,

wood = burned to produces energy.

Food waste = burned to generate the energy which is also used in power plants.

Agricultural crops = also converted as liquid biofuels.

2) Hydropower.

Use of water to generate electricity.

In hydropower plants energy from flowing water is converted into electricity. The whole system consist of three main parts.

A reservoir: Which store the water.

Dam = which control the flow of water.

Power plant = which convert the energy into electricity.

3) Renewable:

Able to be recycled or replenished in a short period of time.

Renewable materials are used and can be generated again to be used again. These are materials which can be recycled again. The example include biomass.

4) Turbine:

Engine with large blades.

It is the rotatory machine which perform its function using fluid action. It consist of large circular blades. The moving fluid hits on the blades in turn blades produces rotational energy to the rotor which helps to create electricity.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
