Question

Liquid on heating becomes gas because its

a. intermolecular force of attraction increases
b. intermolecular space decreases
c. kinetic energy of molecules increases
d. kinetic energy of molecules does not change​

Answer 1

Answer:

kinetic energy of molecules increases

Answer 2

Tip- The kinetic energy of a substance is clearly a function of its temperature, according to the kinetic theory of gases.

As the particles gather enough kinetic energy to overcome the force of attraction, intermolecular space between molecules rises as liquids are heated.

Explanation: When heated, the kinetic energy of nearby atoms or molecules pulls them away. On average, this pushing of atoms or molecules results in a slightly greater distance between them.
