Why liquids can flow?
Liquids flow because the intermolecular forces between molecules are weak enough to allow the molecules to move around relative to one another. In liquids, the intermolecular forces can shift between molecules and allow them to move past one another and flow.
What do liquids flow?
A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds. Like a gas, a liquid is able to flow and take the shape of a container. Most liquids resist compression, although others can be compressed. Water is, by far, the most common liquid on Earth.
Why do liquids flow class 9?
Because of more space between particles and more kinetic energy than solids the particles of liquids slide over one another. These characters make a matter to exist in liquid state. Liquid can flow because its particles can slide over one another.
What are fluids Class 9?
Pressure in fluids : A substance which can flow is called a fluid. All liquids and gases are thus fluids. 3. The resultant upward force experienced by a body when immersed in a fluid is called buoyant force or upward thrust.
What is the plasma state of matter Class 9?
Like gases, plasmas have no fixed shape or volume, and are less dense than solids or liquids. But unlike ordinary gases, plasmas are made up of atoms in which some or all of the electrons have been stripped away and positively charged nuclei, called ions, roam freely.
What is plasma made up of Class 9?
Plasma is the fourth state of matter. Plasma is similar to the gaseous state. The state consists of super energetic and super excited particles in the form of ionized gases. Plasma is made by heating a gas it lose all its electrons .
What is cell wall class 9th?
Cell wall. Cell wall. Cell Wall is found in plant cells outside the plasma membrane. It is a rigid covering made up of cellulose which a complex substance is providing structural support to the plants. The contents of the cell wall contracts during loss of water in plant cells by the process of osmosis.
