Question

When the temperature of a body increases

• A. intermolecular forces between particles increases
• B. intermolecular spaces between particles increases
• C. movement of the particles increases
• D. mass of the particles increases

Answer 1

Answer: (B), (C)

The correct options are
B

intermolecular spaces between particles increases

C

movement of the particles increases

The temperature of an object is the measure of the total kinetic energy of the constituent particles that make up the object. The kinetic energy of the particles is associated with their movement. Whenever the temperature has increased the movement of particles increases thereby increasing the intermolecular spaces between them. Hence on increasing temperature, intermolecular forces reduce. The mass of an object remains constant everywhere in the universe.
