Question

Identify the type of energy involved in each step:

You flip on the switch on a lamp.
The lightbulb lights up.
The lightbulb causes the lamp shade to melt.

Answer 1

If you are turning on a lamp that is kinetic energy

If a light bulb lights up that is electric energy. if something is being melted it is endothermic energy.

Answer 2

1. You flip on the switch on a lamp: Electrical energy.
2. The lightbulb lights up: Light energy.
3. The lightbulb causes the lamp shade to melt: Thermal (heat) energy.

Flipping the lamp switch initiates the flow of electrical energy through the circuit. The lightbulb then transforms this electrical energy into radiant light energy, illuminating the surroundings.

However, not all energy is converted into light; a portion is dissipated as thermal energy, causing the lightbulb to generate heat. This thermal energy can lead to the lamp shade melting, illustrating the conversion of electrical energy into both light and heat.

In this sequence, electrical energy serves as the primary source, with subsequent transformations into light and thermal energy, demonstrating the interconnected nature of energy conversions in a simple yet dynamic system.
