Explain what happens at the particle level when a solid melts

Physics
1 answer:
Scilla [17]4 years ago
8 0
Melting occurs when a solid is heated and turns to liquid. The particles in a solid gain enough energy to overcome the bonding forces holding them firmly in place. Typically, during melting, the particles start to move about, staying close to their neighbouring particles, then move more freely.

What are the two main types of energy?
djyliett [7]

Answer:

Fourth option

Explanation:

They're many different types of energy, from chemical and mechanical to heat and solar energy. But the two most basic types of energy are "kinetic and potential energy" or the fourth option. Kinetic energy is the energy an object has when it is in motion, while potential energy is the energy an object has when it's as rest. These two specific types of energies are the most basic and you can even convert them into many different types of energies, like heat or electrical energy.

Hope this helps.

Two particles with different charges are on the same equipotential line. Do these particles have the same electric potential ene
emmainna [20.7K]

Answer:

both charges will have different potential energies that will depend upon the charge magnitude.

Explanation:

It is given that both the charges are on the same equipotential line which means the potential V at which the two charges are is same.

Now the potential energy of a charge at potential V is given by

q×V where q is the charge value

Thus Higher the charge value for a given value of potential , higher will be the potential energy

Thus the larger charge will have higher potential energy and not the same.
