The phenomenon in which an electron is removed from the metal when light beam (photons) incident on the metal is known as:

If a glass rod is rubbed with silk cloth, glass rod will loose some electrons and become

By applying pressure to certain crystals electrons are driven out of their orbits in the direction of force. This effect is called:

Rochelle salts is a piezoelectric material:

Heating of two different metals which are joined together will result in the flow of electrical current between these metals. This process is Known as:

The light energy applied on some materials which are poor conductors behave as a better conductors. This process is known as:

Freeing of electrons from the hot surface causing the electrons to escape is known as Thermionic emission:

Thermocouples is used to measure the temperature:

Which of the following is produced due to the friction between the two bodies:

When a stationary open conductor is cut by variable magnetic field ___ will be induced in the conductor

Combining chemicals with certain metals causes a chemical reaction that transfers the electrons. This Phenomenon is observed in Electrical Batteries
