Who invented the lava lamp?
Craven Walker invented the fad Lava Lamp in post WWII England
What is the blob in a lava lamp?
Wax.
What did the first lamp look like?
it had lava in it :)
What can an abstract include about lava lamps?
that a lava lamp can be a good product to use when your doing a project.
Why was the lava lamp invented?
It was invented to bring happiness.
How does convection works?
this is like warm, less dense air rises while cool more dense sinks. This is like the lava lamp the hot "lava" floats up to the top and and the cooler "lava" sinks down to the bottom and heats up and rises and the cooling stuff at the top is now sinking
Why does Lava in a lava lamp rises and sinks?
The 'lava' in a Lava Lamp is actually a chemically treated wax. The clear (sometimes colored) liquid is water. When the lamp is turned on the metal coil inside the glass chamber is heated by the light bulb. The reason it sinks and rises is because when the molecules inside the wax get heated up and speed up and expand. This causes them to become less dense than the water causing them to rise. When they are at the top the molecules slowly get colder and they slow down which makes them more dense than the water, so the wax sinks.
What is the science behind a lava lamp?
A lava lamp is a pretty interesting thing, when it is cool, it looks like it's made of candle wax, because it is. Wax is strange, because when it is hot, it rises, but when it is cool, it sinks, so the bulb at the bottom heats the wax, and it floats to the top, but at the top, when it starts to cool down, it sinks. cool huh?
What causes the movement of the liquid in a lava lamp?
Convection is when hot substances rise and cool ones sink. The colored wax heats up at the bottom of the lamp where the bulb is, then rises up, cools, and sinks again.
Why do the blobs of wax rise and fall in a lava lamp?
Convection currents. The hot wax is less dense so it rises. When it reaches the top it begins to cool, becoming less dense and it sinks.
How does wax in a lava lamp work?
The "lava" is a mixture of carbon tetrachloride, mineral oil and paraffin wax. The liquid it floats in is water. The light source is a 40-watt light bulb. When the bulb melts the wax, it will do the lava thing on its own.
A certain type of lamp contains colored liquids these liquids form globs that break off and rise to the top of the liquid the glob rises due to what?
It is called a "lava lamp" and the effect is caused by the heat of the bulb in the lamp causing one of the liquids to warm up and become less dense than the other (it is denser in the cold state). The less dense glob then rises up and breaks off and travels to the top of the lamp where it cools then sinks once again to the bottom of the lamp.
What are the results and conclusion of a lava lamp?
I am a former student and i did this project in the 7th grade and i got 1st place so the conclusion is that when the lava sinks and floats those are chemical reactions.
What is the cause of tectonic plates?
One suggestion for the cause of plate tectonics is mantle convection which is the result of cooling and heating magma. You could think of mantle convection much in the same way lava flows in a lava lamp. Lava rises in a lava lamp because it heats up and becomes less dense. While at the top of the lava lamp, the heated lava begins to cool (because it's further away from the heat source (e.g. light) at the bottom) becoming more dense and then sinks back down to the original heat source where it will be reheated. This mantle convection is thought to work somewhat like a large conveyor belt in which the plates sit, moving them along.
What is inside a lava lamp?
Inside a lava lamp there is wax.
What area is a lava lamp in biology chemistry physics or earth?
A lava lamp is a study in physics. The lamp functions on density and that density or mass as it is called, changes with the addition of heat to the container. When heat is applied the substance that floats changes to lighter mass and begins to rise. When it reaches the top where it is cooler, it gets dense and sinks.
Is a lava lamp a compound or a mixture?
A Lava lamp is amixture of compounds.
