The vapour pressure is the pressure of the vapour above the sample liquid in a closed container. The vapour pressure is determined by the type of... View Article
The energy is stored in the form of potential energy in a compressed string. The potential energy stored by the string is also called strain... View Article
The statement of the first law of thermodynamics was given by Rudolf Clausius in the year 1850. According to the first law of thermodynamics the... View Article
The minimum energy needed for photo-emission of the electrons is called work function. The work function depends on the material. The minimum... View Article
Electric current is due to the flow of electrons from the negative terminal to the positive terminal. While conventional current is due to the... View Article
Inertia is the tendency of an object to continue in the state of rest or of uniform motion. The object resists any change in its state of motion... View Article
Distance divided by time is the rate of change of position or speed on the object. Speed is a scalar quantity. The SI unit of speed is m/s.... View Article
In an open system, the pressure is called atmospheric pressure. When the atmospheric pressure is low then the vapour pressure required to reach... View Article
Gravity is not centrifugal force. The direction of gravity is opposite to that of centrifugal force. The gravitational force pulls the object... View Article
The latent heat of vaporization of water means the amount of heat required to break the intermolecular forces and convert it into the gaseous... View Article
The basic difference between the Compton effect and the photoelectric effect, the Compton effect occurs on the free electrons while the... View Article
The significance of the first law of thermodynamics is listed below It gives the relationship between heat and work. It is merely the law of... View Article
There is no change in the inertia when the velocity is doubled. Inertia is dependent only on the mass of the object. When the velocity of the... View Article
A concave lens is thinner in the middle and broader at the ends. The concave lens diverges or bends the refracted rays outwards because of its... View Article
According to Boyle's law, at a constant temperature, the volume and pressure are inversely related. When the volume decreases the particles will... View Article
