The answer should be D because as kinetic energy is being applied the particles of the solid vibrate about their mean position. At the increase of K.E further increase in vibration is observe until the Vibrations becomes equal to the intermolecular bonds of the solid it melts.
D ansa is a bcos intermolecular force holds the particles of a solid together so when the particles acquire more k.e the particles are able to break d bond thus making d solid to melt
A solid begins to melt when the **energy of vibration of particles of the solid equals the intermolecular forces**. So, the correct answer is **D**.
This is because melting occurs when the particles of a solid substance have enough energy to overcome the intermolecular forces that are holding them together in their rigid structure. This energy is provided by the increase in temperature, which increases the kinetic energy and hence the vibrational energy of the particles. When this vibrational energy becomes equal to the intermolecular forces, the particles start to move more freely, leading to the phase transition from solid to liquid.
The answer is A. constituent particles acquires a greater kinetic energy.
Here's why:
* Kinetic Energy: Think of kinetic energy as the energy of motion. In a solid, the tiny particles that make it up are always vibrating, even if just a little.
* Melting: When you heat a solid, you're giving those particles more energy. This makes them vibrate faster and faster.
* Breaking Free: Eventually, they vibrate so much that they can overcome the forces holding them together in a solid structure. That's when the solid starts to melt and turn into a liquid.
So, when the particles get enough kinetic energy to break free from their fixed positions, the solid melts!
A:
A solid begins to melt when the kinetic energy (vibrational energy) of its particles becomes high enough to overcome the intermolecular forces holding them in a rigid structure. At the melting point, the increased vibrational energy allows particles to break free from their fixed positions and move more freely, transforming the solid into a liquid.
