Question

With the supply of heat energy to matter, the kinetic energy of its particles:

• A. decreases
• B. increases
• C. remains same
• D. cannot be said

Answer 1

The correct option is B

increases

• When heat is supplied to any matter, the heat energy increases the motion of the particles of the matter due to increase in energy of particles.
• The energy possessed by the motion of a substance is called its kinetic energy.
• Hence the kinetic energy of the particles increases on heating the substance.
