How do you prove that it is the wattage and not the physical size of a light bulb that matters for energy use?
Energy use is measured in watts. The watts used by a light bulb is on the package or the bulb. Find bulbs with the same wattage but different physical sizes if you want to prove this.
Is a light bulb matter?
Yes, a light bulb is matter.
Why is the light bulb not a closed system?
it is a closed system. no matter or energy flows across the boundary
What transformations occur in a light bulb?
In a light bulb, electrical energy is transformed into light energy and heat energy.
What is the source of energy in a light bulb?
Electricity is the source of energy in a light bulb.
Why is a light bulb not a closed system?
it is a closed system. no matter or energy flows across the boundary
What is most of the energy produced by a light bulb?
Most of the energy in a light bulb is heat energy.
When energy runs through a light bulb what kind of energy does the light bulb produce?
A light bulb uses electrical energy, and produces light, as well as heat.
What energy occurs in the light bulb?
light and heat energy occur in a light bulb when it is turned on.
What energy transformation occurs in a bulb?
In a light bulb, electrical energy is transformed into light energy and heat energy.
Is a light bulb an example og electromagnetic energy?
A light bulb is not an example of electromagnetic energy, but the light which the bulb gives off is an example of electromagnetic energy.
When the light bulb is lit electrical energy is changed into light energy and?
When lighting a light bulb, it is changed into light and heat/thermal energy.
