Why are computer models useful in studying phenomena in the universe?

Computer Models are used to study the complex phenomena in the universe.

Explanation:

The term 'models' can be defined as a representation of something that is real. A model is used to learn the phenomena of the natural world for easy understanding of it.

The computer models are used to study the large and complex data in the universe. These models are used to perform various calculations that, in real, would take years to do. It helps in studying the changes in variables, which in turn helps the scientist to know of any climatic change, or other changes in the nature.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

the dissolution of polymer can be thermodynamically described in 2 steps.
