kinetic and potential energy.. help =X?

Question

1) what happens to the kinetic energy of the ice during the process of melting? explain.

2) what happens to the potential energy of ice while it melts? explain.

thanks

Answer 1

When ice melts it means that the ice is getting warmer. The molecules are steadily speeding up. Since KE is the energy of motion, the KE would increase.

Since energy is conserved, an increase in KE would mean a decrease in PE.

Answer 2

This is an interesting question. Do you know that kinetic energy is energy of motion? Unless the ice is in motion it has no kinetic energy. Potential energy in ice? Whatever do you mean?

I suppose you could be talking about the potential energy of the crystal bonds of the ice itself. Whatever energy was contained in these bonds more energy was needed to break the bonds. This energy only breaks the bonds that make the ice solid causing the ice to melt. The key word here is ‘melt’. Energy is needed to melt the ice. So while the energy added to the ice breaks the bonds of the crystals of ice melts without a change in temperature.

If this does not answer your question, perhaps it will help you ask another one that is closer to what you are trying to figure out.

Answer 3

All waves are kinetic ability. And, radio, x-, and ultraviolet waves are all different sorts of electromagnetic waves. So, all of those are kinetic ability. Kinetic ability is often damaged down into radiant ability, sound ability, ect. a million. radiant 2. action 3. radiant 4. sound 5. action 6. radiant 7. radiant
