Does a lemon or apple have a higher pH level to light up a light bulb?
A lemon has a lower pH level (around 2) compared to an apple (around 3) due to its higher acidity. The acidity of the lemon allows it to conduct electricity better and light up a light bulb when used in a simple battery setup.
Is a light bulb a compound?
No. The light bulb is two words, not a combination of light and bulb.
Is a light bulb a reversible change?
No, a light bulb is not a reversible change. When the filament inside the light bulb heats up and emits light, it undergoes a chemical change and cannot be easily reversed.
Can you light up a bulb using salt and water?
No, salt and water cannot be used to directly light up a bulb. However, a battery or an electric circuit incorporating salt water could potentially generate electricity to light up a bulb.
What element is essential in a light bulb?
The essential element in a light bulb is tungsten. Tungsten is used as the filament inside the bulb, which heats up and emits light when an electric current passes through it.
How does a lemon power up a light bulb?
A lemon can power up a light bulb by acting as an electrolyte in a chemical reaction with the metals in the light bulb. When zinc and copper electrodes are placed in the lemon, a chemical reaction creates an electrical current that can power a small LED light bulb.
How big does a lemon have to be to light up the light bulb?
normal size
How big does a lemon have to be to light up a light bulb?

How big does a lemon have to be to light up a long light bulb?
A lemon needs to be large enough to generate about 1.5-2 volts of electricity in order to light up a small LED bulb. A regular lemon from the store should be large enough for this purpose.
Is a lit light bulb mechanical or nonmechanical?
A lit light bulb is nonmechanical because it does not involve moving parts. When electricity flows through the filament, it heats up and produces light, but there is no mechanical process at work.
Does a lemon or apple have a higher pH level to light up a light bulb?
A lemon has a lower pH level (around 2) compared to an apple (around 3) due to its higher acidity. The acidity of the lemon allows it to conduct electricity better and light up a light bulb when used in a simple battery setup.
How did the bulb feel after lit up 2 minutes?
bulb feel after being lit up for 2 minutes
How can a make a lemon light up a light bulb?
lemon can power a light bulb b'coz lemon contains citric acid which can serve as an electrolyte if the connections r complete it undergoes elecrolysis & sets up an electrolytic cell.
Is the light bulb that Thomas Edison invented still lit to this day?
No, the original light bulb that Thomas Edison invented is not still lit today. The filament in the bulb would have burned out a long time ago. However, there are modern versions of light bulbs that are based on Edison's original design.
Does a light bulb heat the air around it by conduction or radiation?
A light bulb heats the air around it through radiation. As the filament heats up and emits light, it also emits infrared radiation that warms up the air in its vicinity. This is why you can feel the warmth when you are near a lit light bulb.
Why do light bulbs stay lit?
Light bulbs are designed to produce light when electricity passes through the filament, causing it to heat up and emit photons. As long as there is a continuous flow of electricity, the filament will continue to glow and the light bulb will remain lit.
What is the past tense of light up?
The past tense of "light up" is "lit up."
