either by radiation, conduction, or convection.
The heat absorbed when a solid liquefies is called latent heat of fusion. This heat is used to break the bonds between the solid particles, allowing them to move freely and change from a solid to a liquid state.
a solid melts (and the liquid remains at the temperature of the solid).
A liquid becomes a solid when there is less heat. When a liquid loses heat, its particles slow down and come closer together, eventually forming a solid structure.
When this happens,the liquid loses all its heat & becomes solid.
Heat will cause a solid to melt into a liquid.
Of course heat is added because you are turning solid which is like ice to gas which is water vapour !!
When heat is applied to a solid, the temperature of the solid increases, causing the particles within the solid to gain energy and vibrate more rapidly. Eventually, the solid may reach its melting point and transition into a liquid state.
Most usually, heat expands a solid, making it less dense.
Heat energy is needed to melt a solid because it provides the molecules in the solid with enough kinetic energy to overcome the forces holding them in a rigid structure. The specific heat energy required to melt a solid at its melting point is called the latent heat of fusion.
When a solid absorbs heat, its temperature increases and the particles within the solid vibrate more rapidly, leading to an expansion in volume. When a solid releases heat, its temperature decreases and the particles vibrate less, causing the solid to contract in volume.
When heat is supplied to a solid, the heat energy causes the particles within the solid to vibrate more rapidly. This increase in vibration disrupts the regular arrangement of particles, leading to the solid expanding as the particles move further apart.
Actually, a liquid becomes a solid when it loses heat, not when it gains heat. When heat is removed, the molecules slow down and eventually arrange themselves into a solid crystalline structure.
