Answer:
The hood of a car heats up after the car has been running for a while because the engine gets heated up.
What causes this heat is the friction in the internal parts of the engine. The resistance due to the friction in the internal parts of the engine, heat energy is produced. Heating up off the car's engine is a serious issue. To control this heat, cooling system does its job.
A leak in the cooling system or a blockage in the cooling system are considered indirect causes of overheating.
The engine oil itself plays a part in cooling down the engine by lubricating the engine parts and reducing the friction.
