During the melting of solids, the interparticle space ____________________

• With the increase in temperature, the kinetic energy of particles increases, therefore interparticle space increases and hence, solid starts melting.
• The process of Change of a solid into a liquid when heat is applied is known as melting.
• In a pure crystalline solid, this process occurs at a fixed temperature called the melting point

So, during the melting of solids, the interparticle space increases.
