A torch converts chemical energy from the batteries into electrical energy, which powers the light bulb. The light bulb then converts the electrical energy into light and heat energy, which is emitted as visible light and warmth. Some energy is also lost as thermal energy due to inefficiencies in the conversion process.
A diagram showing the transfer of energy between organisms is called a food web or an energy pyramid. It illustrates the flow of energy through different trophic levels in an ecosystem, showing how energy is transferred from producers to consumers.
A hairdryer typically converts electrical energy into heat and kinetic energy. The energy transfer diagram would show electrical energy input as the primary source, which is then converted into heat energy for drying hair and kinetic energy for generating airflow.
The energy transfer diagram of a Bunsen burner shows the input energy as chemical energy from the gas source, which is transferred to heat energy through combustion in the burner. This heat energy is then transferred to the surroundings through convection, radiation, and conduction.
To draw an energy transfer diagram for a firework, you can start with the chemical energy stored in the firework chemicals. When the firework is ignited, this chemical energy is converted into thermal (heat) energy, light energy, sound energy, and kinetic energy as the firework launches and explodes. Each arrow in the diagram represents the flow of energy from one form to another.
A TV converts electrical energy into light and sound energy. The energy transfer diagram would show the input of electrical energy from the power source, which is then converted into light energy by the screen and sound energy by the speakers. Some energy is lost as heat during the process.
