Thermal expansion takes place in all states of matter. The gases expand more than liquids and liquids expand more than solids for the same amount of heat. Thermal...
Heat is the most common form of energy. Heat can be transferred from one place to another by means of conduction, convection and radiation. It can be converted...
Specific heat capacity, often simply called specific heat, is a measure of the amount of heat energy required to raise the temperature of a substance by a certain...
When we move our fingers through any liquid we experience a resistance. This is because liquid offers a frictional force. The resistance offered by fluids (liquids as well...
A glass tube with a very fine uniform bore is called a capillary tube. When a capillary tube is dipped vertically into a liquid contained in beaker, the...
Surface tension of a liquid is defined as the tangential force per unit length acting at right angles on an imaginary line drawn on the surface of the liquid....
Sun-synchronous orbit or a heliosynchronous orbit very important because of its particular importance to satellites intended for remote sensing and military applications. A sun-synchronous orbit is one that...
The Polar Orbit is not much suitable for communication purposes because it moves in a different direction than that of direction of earth’s rotation. So, the use of...
