Question

At what temperature will a solid melt?

O
A. The temperature at which intermolecular forces push the
molecules apart
O
B. The temperatud at which the kinetic energy breaks the
intermolecular attractions
O
c. The temperature at which the pressure forces molecular motion to
stop
D. The temperature at which the atomic bonds within the molecules
are broken

Answer 1

Answer: B) the temperature at which the kinetic energy breaks the intermolecular attraction

Answer 2

A solid will melt at the temperature at which the kinetic energy breaks the inter-molecular attractions.

Step-by-step explanation:

The melting point is the state at which "a substance changes its temperature from a solid to liquid". At the melting point temperature, there is an equilibrium between the both the solid and the liquid phase. When the solid particle is heated by increasing the temperature the particle in the solid vibrate quickly and it absorbs kinetic energy.

It leads to the breaking of the organisation of particle in between the solid and that leads to the melting of solid. Thus, at the melting point, the kinetic energy breaks the inter-molecular attractions.
