In a car engine, chemical energy stored in fuel is transformed into thermal energy through combustion. This thermal energy then creates pressure and forces the engine's pistons to move, converting it into mechanical energy. Finally, this mechanical energy is used to power the vehicle's wheels, enabling movement.
chemical energy is converted to kinetic energy
True
The chemical energy is transformed in kinetic energy.
Chemical energy is converted into mechanical energy.
True
The most common unintentional energy transformation is the conversion of mechanical energy into thermal energy through processes like friction, which occurs when two surfaces rub against each other and generate heat. This transformation is often seen in everyday activities such as walking, driving a car, or using electronic devices.
Three conversions in energy transformation may include chemical energy in gasoline converting to thermal energy in a car engine, then to mechanical energy to move the car, and finally to kinetic energy as the car moves.
Energy transformation has occurred.
Energy transformation occurs when energy changes from one form to another, such as from potential to kinetic energy or from chemical to thermal energy. This process is governed by the laws of thermodynamics, which dictate that energy cannot be created or destroyed, only transferred or converted into different forms. Energy transformations are common in everyday activities, like when a car engine converts chemical energy from fuel into kinetic energy to move the vehicle.
Inside a battery, chemical energy is transformed into electrical energy. When the battery is connected to the igniter in a car engine, this electrical energy is then converted into thermal energy (heat) through a spark. This spark ignites the air-fuel mixture in the engine's combustion chamber, leading to mechanical energy that powers the engine.
chemical (burning of the gas) to mechanical( the cylinder pressure turning the crankshaft).
A moving car transforms chemical energy from gasoline into kinetic energy of motion and heat energy through combustion in the engine. Additionally, some mechanical energy of the car's motion is transformed into thermal energy due to friction with the road and air resistance.
