Question

How is the kinetic energy of the constituent particles of matter affected by the change in temperature?

Answer 1

Kinetic energy — The energy that is produced by the movement of the particles is considered kinetic energy

• Kinetic energy is dependent upon the intermolecular forces between the particles
• Intermolecular forces are higher in solid following liquid and weaker in gas
• Higher the intermolecular forces lower the kinetic energy
• kinetic energy is also dependent upon the temperature
• The higher value of temperature lowers the strength of intermolecular forces and higher the kinetic energy of the particles
• So, when we increase the value of temperature kinetic energy also increases and vice versa

Thus, in this way, the kinetic energy of the constituent particles of matter is affected by the change in temperature
