What are Manometer & Piezometer? Manometer and Piezometer are pressure measuring equipment made of glass tubes which are directly mounted in the pipeline through which a liquid flows. These devices are used for measure ofRead More →
How Friction acts on Inclined Plane? Friction on an inclined plane depends upon the angle of inclination of the plane. As the angle of inclination increases, the friction force decreases. To understand this, consider aboutRead More →
What are Laws of Friction? Friction is a natural phenomenon which resists the motion of a solid material body upon another solid surface or liquid mass or gaseous atmosphere. Therefore, if there is a relativeRead More →
What is the Second Law of Thermodynamics? The first law of thermodynamics states that, energy can neither be created nor destroyed. The total quantity of energy in the universe remains same. The Second Law ofRead More →
What is Frictional Force? Friction is a natural phenomenon which resists the motion of a solid material body upon another solid surface or liquid mass or gaseous atmosphere. Therefore, if there is a relative motionRead More →
What is the Principle of Moment? Principle of moment states that – If a number of co-planer forces are in static equilibrium, then the algebraic sum of their moments about any point in their planeRead More →
What is Moment of a Force? If a body is free to move and a force is applied on that body, then the effect of this force will produce some action or movement in theRead More →
What is called Degree of Freedom of molecules? Degree of freedom of a system is defined as the total number of independent ways in which the particles of the system can absorb energy. In general,Read More →
What is the Kinetic Theory of Gases? Kinetic theory of gases is used as a framework for understanding gases and predicting their behavior. It links the microscopic behavior of gas molecules to the macroscopic propertiesRead More →
What is Ideal Gas Equation? An equation which gives a relationship between pressure , volume and temperature of any gas, is called Ideal Gas Equation. Consider about a gas of mass . According to Boyle’sRead More →
What is called a Thermodynamic Process? A process in which at least two or more state variables of a system got change, is called a thermodynamic process. For example – Consider that, in a pistonRead More →
What is a Transformer? A transformer is an electrical device used to convert low alternating voltage at higher current into high alternating voltage at lower current. Therefore, a transformer is used to increase or decreaseRead More →
What is called an LCR circuit? A circuit containing an inductor of pure inductance , a capacitor of pure capacitance and a resistor of pure resistance joined in series across an AC supply is calledRead More →
What is an Alternating Current? An electric current in which the magnitude of current and polarity both changes periodically with time is called an Alternating Current (AC) Most of electric appliances run on alternating current.Read More →
What is Thermodynamics? Thermodynamic is the branch of science which deals with concepts of heat and temperature and the inter conversion of heat and other forms of energy. The word “thermodynamic” actually meant for “heatRead More →
