Could the universe be an open system?

Universe is neither an open nor a close system . It is an isolated system i.e neither energy nor mass can be transferred.

What is time infinite or finite?

From Wikipedia, the free encyclopedia. Temporal finitism is the doctrine that time is finite in the past. The philosophy of Aristotle, expressed in such works as his Physics, held that although space was finite, with only void existing beyond the outermost sphere of the heavens, time was infinite.

What does infinite space mean?

The quality or condition of being infinite. 2. Unbounded space, time, or quantity. 3. An indefinitely large number or amount.

Why is universe a closed system?

The universe itself is a closed system, so the total amount of energy in existence has always been the same. The forms that energy takes, however, are constantly changing. The sum of these is called mechanical energy. The heat in a hot object is the mechanical energy of its atoms and molecules in motion.

Why does the earth system resemble a closed system?

A closed system is a system in which only energy is transferred with its surroundings. An open system, however, is a system in which both energy and matter can transfer. The earth is a closed system because only energy is naturally transferred outside the atmosphere.

What is meant by a closed system in physics?

In physics In nonrelativistic classical mechanics, a closed system is a physical system that doesn’t exchange any matter with its surroundings, and isn’t subject to any net force whose source is external to the system. A closed system in classical mechanics would be equivalent to an isolated system in thermodynamics.

Why would the Earth not be considered a closed system?

The Earth is made up of chemical elements – think of the periodic table. That is a list of all basic elemental materials on our planet. Because of gravity, matter (comprising all solids, liquids and gases) does not leave the system. It is a closed box.
