What is the coded properties of liquid solid and gas

Sophie [7]

Gas :

A state of matter that has no definite shape as well as no definite volume is called gas: it occupied all the space container which it is kept.

Liquid :

A state of matter that has a definite volume but no definite shape is called liquid. it occupies or attains the shape of the container in which it is kept.

Solid:

A state of matter that has both definite shape and volume is called solid.

Liquids are less common than solids, gases, and plasmas. The reason is that the liquid state of any substance can exist only within a relatively narrow range of temperature and pressure.

the same substance may exist in three states. for example, water in the form of ice is solid; in the form of steam is gas, while a usual form of water is liquid.

it is the inter-molecular distances or spaces between the molecules, which makes difference among the three states. in solids, the molecules are closely packed with one another and have minimum inter-molecular distance. in gases, the molecules are free from one another and have very large inter-molecular distance. in liquids the situation is intermediate. they have large inter-molecular distance as compared to solids but much less than gases.

Drag each item to indicate whether it is related to Aristotle's or Ptolemy's model of the solar system, or to both. Some items m

Romashka-Z-Leto [24]

Answer:

Aristotle's Model :

geocentric

planets fixed on nested spheres

Ptolemy's model:

geocentric

planets fixed on epicycles

accurately predicted the positions of the planets

Explanation:

Let's begin by the fact both models are geocentric and make a brief explanation of them:

Aristotle's Model :

Aristotle built his model based on observations and philosophical assumptions, not on measurements or calculations, then he mistakenly thought the Earth was the center of the universe.

So, according to this model, the universe was spherical and finite, with the Earth immobile at its center, composed of the four fundamental elements (made up of spherical layers): ground, water, air and fire; and the Sun along with the fixed planets in their respective concentric spheres (also called nested spheres) revolving around the Earth.

Ptolemy's model:

Ptolemy's model of the universe was also geocentric, placing the Earth motionless in the center of the known universe and was the accepted model for a long time during the Middle Ages.

In this sense, ccording to Ptolemy's model of the universe our planet remains stationary while the other planets, the Moon and the Sun describe complicated orbits around it (called epicycles).

However, this model predicted with an acceptable accuracy for that time the motion of the known planets, until Copernicus appeared with the revolutionary Heliocentric model.
