solids liquids gases introduction to class 6​

Answer 1

Answer:

Solid , Liquids & Gases

Explanation:

Solid is the state in which matter maintains a fixed volume and shape ; liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume ; and gas is the state in which matter expands to occupy the volume and shape of its container . Solids , liquids and gases are known as states of matter . Water , ethanol , household bleach , blood , paint , milk , gasoline , mineral oil , acetone and butyl alcohol are examples of liquids . Liquids' properties allow them to flow or be poured easily into containers . Liquefied gas ( sometimes referred to as liquid gas ) is a gas that has been turned into a liquid by cooling or compressing it . Examples of liquefied gases include liquid air , liquefied natural gas , and liquefied petroleum gas .  Solids are objects that keep their own shape and do not flow in a given temperature . Ice is a solid but when it melts it becomes a liquid . Other examples of solids are cars , books and clothes . Solids can be different colors and textures , and they can be turned into different shapes , for example clay . A gas is a state of matter with no fixed volume or shape . Examples of gases include air , water vapor , and helium . Examples of liquids are water at room temperature ( approximately 20 ºC or 68 ºF ) , oil at room temperature , and alcohol at room temperature . When a liquid is heated , the atoms or molecules gain kinetic energy .

Answer 2

Answer:

solid

• In solids, particles are tightly or closely packed.
• The gaps between the particles are tiny and hence it is tough to compress them.
• Solid has a fixed shape and volume.
• Due to its rigid nature, particles in solid can only vibrate about their mean position and cannot move.
• Force of attraction between particles is adamant.
• The rate of diffusion in solids is very low.
• An example of solids: solid ice, sugar, rock, wood, etc.

Liquid

• In a liquid state of matter, particles are less tightly packed as compared to solids.
• Liquids take the shape of the container in which they are kept.
• Liquids are difficult to compress as particles have less space between them to move.
• Liquids have fixed volume but no fixed shape.
• The rate of diffusion in liquids is higher than that of solids.
• Force of attraction between the particles is weaker than solids.
• Example of a liquid state of matter: water, milk, blood, coffee, etc.

Gas

• In gases, particles are far apart from each other.
• Force of attraction between the particles is negligible, and they can move freely.
• Gases have neither a fixed volume nor a fixed shape.
• The gaseous state has the highest compressibility as compared to solids and liquids.
• The rate is diffusion is higher than solids and liquids.
• The kinetic energy of particles is higher than in solids and liquids.
• An example of gases: air, helium, nitrogen, oxygen, carbon dioxide, etc.
