Is Lava Lamp homogeneous or heterogeneous?

Why is a lava lamp a mixture?

Oil floats because it is less dense than water. Oil and water don’t mix because water molecules are not attracted to oil molecules. … Changes in density as gas is added to or taken away from water cause it to float up and sink down through the oil. Thus the lava lamp is created!

Where is heat transferred by conduction in a lava lamp?

Conduction is the transfer of heat through direct contact (in this case, metal coil contact with the “lava” at the bottom of the lava lamp). Convection is the transfer of heat through movement such those in a flowing medium (such as liquids or gases, or in this case as the “lava” rises in a lava lamp).
