Why a solid melts when it is heated?

Answer 1

When you heat up a solid, because heat is a form of energy, it gives kinetic eergy to the particles which make up the solid. The particles which make up a solid are densely packed and the kinetic energy makes them move around and this means thay break apart and this is what a liquid is unless its heated so much that the particles are so far apart that it is a gas. Sorry for the bad explanation

Answer 3

Heat is a form of energy. When a solid is heated for long enough, the individual particles have enough energy to weaken/destroy the bonds that keep the particles together. The new formation is not the organised solid structure that it once was, and forms a new state of matter, which we call liquid. The process, of course, is called melting, and is the change of state from a solid to a liquid.

Answer 4

From what i know, heat energy that gets transferred to the object is used to break intermolecular bonds within the object, and while these bonds are breaking, no increase in temperature can be recorded. Which is why we all know that water boils at 100oc, and doesn't change temperature during this process.

Answer 5

[bear with me because my answer might be a bit confusing.]

a substance melts because its particles have enough energy to change to a different state. (in this case liquid state)

the higher the temperature, the more energy the particles have. the more energy the particles have, the faster they can move. When they have enough energy, they can change into the next state.

if u still don't understand, think of it like this:

1) gas
2) liquid
3) solid

(gas being when the particles move the fastest)

if you are a solid ice cube, your particles move slowly because they don't have much energy. Now lets say you want to become a liquid. To go become a liquid you need more energy. One way to increase energy is by increasing temperature.

When you increase the temperature, your particles get more energy to move around. When you get enough energy, you turn into a liquid!

to turn into a gas u need more energy, which you can get by increasing temperature.
(ex. hot shower)

Answer 6

solids melt when they are heated and their particles acquire more kinetic energy,vibrate more violently and the force of vibration overcomes the binding forces in the solid making their structure to collapse.

Answer 7

When a solid is heated, the addition of heat energy increases the kinetic energy of its particles. This causes the particles to overcome the forces holding them in place in a solid lattice structure, leading to the solid melting and transitioning into a liquid state.

Answer 8

fire/heat makes matter expand the melt away
