What happens when an object freezes?
the particles in the liquid move so slowly that they begin to take on their fixed positions
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 using a ramp make lifting a heavy object easier?
You get mechanical advantage by the slope of the ramp. You move the object horizontally and raise the object slowly as you do so.
Why does the wax in my lava lamp start to stay at the top after a while?
Can someone please help me!!! once i switch it of it floats back to the bottom and i don't know why? The wax and liquid are different densities. Density changes with temperature. When the wax is near the heat source, its temperature increases and it becomes less dense compared to the liquid and then it floats to the top. When it gets to the top, it cools down because it is farther from the heat source. When it cools down, it becomes denser than the liquid, and it sinks. So when you turn off the lava lamp, the wax and liquid cool to room temperature, and the wax is denser than the liquid so it stays at the bottom.
Explain why you can see both a light bulb and a lamp base?
Because when you turn on a lamp the light is so bright that it shines through the material that it is made out of, so you are able to see through it!
Is an lava lamp an opical device and if so what kind?
No, a lava lamp is not considered a type of optical device.
Why do you use water in a lava lamp?
So it can live
Can your lava lamp explode?
Yes, it can explode. It can explode when you leave it on for longer than the instructions say.
What is the hypothesis of a homemade lava lamp?
A lava lamp, however made, is an object, and so the idea of an hypothesis is not applicable. You use an hypothesis in an investigation, which is a process.
How does a lava lamp have a circuit?
People are too busy to make one out of silicon, so they make one out of lava! Then they eat the lava lamp and the circuit comes to a full stop! NOM NOM NOM
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.
Why is the lava at the top of lamp?
Because the lava is heated and it floats to the top. It is heated and the lava gets less dense than the water so again it floats to the top.
Why would a lava lamp interest someone?
It will interest you because they are so fascinating to watch.
Why are lava lamps hot?
Lava lamps get hot because you have to plug them into the wall and wen you do that it creates energy so then your lava lamp heats up and then the stuff inside it can work.
Can you put an A 19 Bulb in your Lava Lamp?
My Lava Lamp said to use an A 15 aplliance bulb. I went to Walmart and they didn't have them so I thought the A 19 replaced it. Worng. The A 19 does not fit. My lava lamp had a sticker iside of it saying what type of bulb to use, but, of course, I bought the wrong one. The A 19 is too tall, the bottle didn;t fit.
Are you ment to leave Lava lamps on over night?
No you do not have to but you can it is completely safe a lava lamp is made to be as a decoration light so you CAN if you want to but you will go through bulbs faster!
Can you describe the bulb in the lava lamp?
Incandesent round mini-bulb designed specifically to fit into lava lamp with appropriate wattage to heat the volume of the lamp to a temperature that melts the wax compound without overheating the liquid volume. Very precise so use only the manufacturer's recommended bulb.
