Question

Write a brief explanation of convection using the terms expansion, density, and gravity.

Answer 1

EXPANSION :- The expansion of the universe is the increase in distance between any two given gravitationally unbound parts of the observale universe with time.

DENISTY :- Mass of a unit volume of a material substance.

GRAVITY :- Is also called the gravitational force, the universal force of attraction acting between all matter.

Answer 2

Expansion- the action of becoming larger or more extensive. Density-he degree of compactness of a substance. Gravity-Sturdy with triple wall structure, these gravity convection ovens carry accurate temperature uniformity as well as air distribution similar to many forced air ovens. Units are well suited for a diversity of drying, baking as well as curing applications
