In a lava lamp, a waxy substance rises and falls repeatedly. What causes the waxy substance to rise? Check all that apply. The waxy substance is cold. The waxy substance is warm. The waxy substance is less dense than the surrounding liquid. The waxy substance is more dense than the surrounding liquid. Convection is occurring.

The waxy substance is warm.

The waxy substance is less dense than the surrounding liquid.

Convection is occurring.

Explanation:

Convection involves heat transfer by the actual movement of the particles of a substance.

When the wax is heated, the waxy substance becomes warm and rises in the lamp. The warm waxy substance is less dense than the surrounding liquid, this process of rising and falling is as a result of convection occurring in the lava lamp.

Explanation:

the answer is b. dilution

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
