Question

As the clump of colored fluid at the bottom of the lava lamp reaches the top, which has increased? its density its temperature the kinetic energy of its molecules the space between its molecules

Answer 1

a

Step-by-step explanation:

density, just took the test

Answer 2

Option A, its density

Step-by-step explanation:

A lava lamp consists of two liquids which have density close to each other and are insoluble as well into each other. Now when heat is applied at the bottom of the lava lamp, the heavier liquid absorbs heat and become less dense. As it density reduces it starts flowing and rises up in the lamp. As the liquid rises it becomes cool and its density rises. With the increase in density, this liquid again settles down.

Thus option A is correct
