Question

identify the types of energy that belongs in each blank in the energy chain diagram below
diesel fuel bulldozer
a (fuel) → b (combustion) → c (movement)
a: blank
b: blank
c: blank

Explanation:

• For A (Fuel: Diesel fuel stores energy in the form of chemical energy because the bonds in the fuel molecules hold potential energy that can be released during combustion.
• For B (Combustion): When diesel fuel undergoes combustion, the chemical energy is converted into thermal (heat) energy as the fuel burns, releasing heat.
• For C (Movement): The thermal energy from combustion is then converted into mechanical energy to power the bulldozer's movement, as mechanical energy is associated with the motion and work done by the machine.

Answer:

• A: Chemical Energy
• B: Thermal (Heat) Energy
• C: Mechanical Energy
