What are two examples of convection?
lava lamp, and a hot stove
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.
What can you do to make a graph for an lava lamp?
how to make a graph for a lava lamp
How long can you keep a lava lamp on for?
It is not recommended to keep the lava lamp on for longer than 10 hours at a time.
Who created the Lava Lamp?
Edward Craven Walker, born in Singapore in 1918, invented the lava lamp in the 1960's.
Is a lava lamp an example of heat transfer by convection?
Yes
What are two examples of convection?

What is a lava lamp circulating lava inside itself?
The "lava" in a lava lamp is just melted colored wax. Convection currents cause blobs of the wax to rise and fall in the clear mineral oil mixture.
What does the liquid inside of a lava lamp consist of?
It is usually wax that melts as the lamp is turned on. When it is heated, it then begins to float around with the convection current created by the heat-generating lamp, thus creating the "lava" effect.
What is a good example of convection besides boiling water or a lava lamp?
the earth's mantle is always moving inside which move the plate on the earth's crusthope that made sense.
Is an lava lamp an example of a emulsion or suspension?
A lava lamp is a suspension because it is a mixture that has drops of a substance in another substance.
What are convection currents?
convectional currents in the mantle are themselves driven by the heat of the core. the heat is partly created of overlaying material. A lava lamp is a perfect example of convectional
How do you get convention in a lava lamp?
The heat of the lamp causes the fluids to heat and expand. The two materials are of different thermal properties and are immiscible.The word you seek is convection.
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.
What is conclusion for a lava lamp experiment?
The conclusion for a lava lamp experiment depends on the thesis. If the thesis talks about the temperature for example the conclusion should reflect that.
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.
Heating food under a heating lamp is an example of heat transfer by?
convection
