Explain the flow of energy (heat) when a solid turns into a liquid.
Answers
Answer:
Heat energy is needed to convert solid into a liquid because heat energy increases the kinetic energy of the particles. ... So it changes into a liquid state. The heat energy that it used to change 1 kg of solid into liquid at atmospheric pressure and at its melting point is called the latent heat of fusion
At melting point of solid, the solids are converted into liquids. During melting the kinetic energy of the particles of the solids increases due to increase in temperature. Due to this the intermolecular forces of attraction in solids decreases and thus solids are converted into liquids.
Melting point of solid:
The temperature at which solid changes to a liquid state.
When we supply heat energy to the ice at 0
o
C.
It will absorb the heat and the forces between the ice particles start breaking and hence ice melts to a liquid state.
The heat absorbed by the ice will increase the kinetic energy of particles of ice.
When a solid is heated the particles gain energy and start to vibrate faster and faster. ... At this point the solid is melting to form a liquid. The particles in the liquid are the same as in the solid but they have more energy.
Answer:
Energy increases on solid turning into liquids.
Explanation:
To change a solid into a liquid you have to heat the solid above its melting point. The atoms absorb this heat energy and start to move more and more. Hence, the atoms of the solid get separated, and eventually, it starts to flow. The molecules in a solid gain sufficient energy to overcome the force of the bonds that hold them in place. Normally, during melting, the particles start to move about, staying close to their adjacent particles, then begin to move more freely. Hence their energy increases on solid turning into liquids.
