The measure of intensity of heat in degrees reflecting the average kinetic energy of the molecules is temperature. Temperature is a quantitative measure of the average kinetic energy of the particles in a substance or system. The higher the temperature, the greater the average kinetic energy of the molecules.
In the classical picture, the total energy of a revolving electron in an atom is not zero as it has both kinetic and potential energy. However, in the quantum mechanical model, the energy of an electron in an atom is quantized and can only take on specific discrete values governed by the principles of quantum mechanics.
Kinetic energy can be expressed by the equation: Ek= ½ mv2. Therefore in addition to speed (v), kinetic energy is also dependent on mass (m).
The average kinetic energy of molecules depends on temperature, which is a measure of the average kinetic energy of the particles in a substance. The kinetic energy of molecules is also affected by their mass and velocity. Temperature and molecular mass have a direct relationship with kinetic energy, while velocity has an indirect relationship.
The total energy of a revolving electron in an atom is the sum of its kinetic energy and potential energy. The kinetic energy is due to its motion, while the potential energy is associated with its attraction to the nucleus via electrostatic forces. The total energy is negative, indicating that the electron is bound to the atom.
The ejected electron possesses kinetic energy as it moves away from the surface.

Temperature is a quantitative measure of the average kinetic energy of the particles in a substance or system. The higher the temperature, the greater the average kinetic energy of the molecules.
The kinetic energy of a body depends on its mass and its velocity. As the mass of the body increases, its kinetic energy also increases. Similarly, as the velocity of the body increases, its kinetic energy increases as well.
Kinetic Energy
The kinetic energy depends on the object's mass, and on its speed.
In the classical picture, the total energy of a revolving electron in an atom is not zero as it has both kinetic and potential energy. However, in the quantum mechanical model, the energy of an electron in an atom is quantized and can only take on specific discrete values governed by the principles of quantum mechanics.
The factor that provides kinetic energy to an electron is the difference in potential energy between the electron's initial and final states. This energy can arise from sources such as electric fields, magnetic fields, or interactions with other particles.
Both are equal.
An object's kinetic energy depends on its mass and its velocity. As an object's mass or velocity increases, its kinetic energy will also increase.
The kinetic energy of a body depends on its mass and its velocity. The kinetic energy of an object increases with its mass and also increases with the square of its velocity.
Temperature is the measure of intensity of heat in degrees, reflecting the average kinetic energy of the molecules in a substance. The higher the temperature, the faster the molecules move, and the more kinetic energy they possess. Temperature is typically measured in degrees Celsius or Fahrenheit.
The increased frequency increases the kinetic energy of the single electron ejected. Remember that the incident light releases a single electron when the threashod frequency is reached
