Physics / More about Solids, Liquids and Gases

We know that all substances are made up of tiny particles called molecules. Sugar is made up of sugar molecules, water of water molecules. Air is mixture of many different types of molecules. These molecules are responsible for various properties of solids, liquids and gases such as conduction of heat, pressure of gases and rise of a liquid through a wick. Learn about molecular or kinetic theory of matter and its application in characteristic properties of solids, liquids and gases.
Do you know which force helps the water drop to remain on surface of a plant or which force is responsible for making of water drop? Force between water drop and plant, which holds water drop on the plant is adhesive force. Force between the particles of water, which holds them together is cohesive force. Learn more about adhesive and cohesive forces.
Do you ever think why a water drop is spherical in shape ? This is due to surface tension-The property of the liquid surface to behave like a stretched elastic membrane is known as surface tension.
Learn the applications of surface tension and know why some liquids wet the solid surface while others do not.
Pressure of a gas is inversely proportional to its volume - This is the only principle used in cycle pumps - When the handle of a bicycle pump is pushed down, a piston inside the pump moves down and compresses the air inside it. This means the volume of the air decreases. Hence pressure increases, and it is able to force its way into the tube(Inside the tyre). Understand Archimedes' principle, floatation and explore your knowledge and understanding.
