When water molecules melt, energy is absorbed. When water molecules evaporate, energy is also absorbed. When water molecules condense energy is released. When water molecules freeze energy is also released.
released
Endothermic reactions are those in which energy is absorbed during the reaction. Exothermic reactions are those in which heat is evolved during the reactions.When ice melts its absorbs energy in the form of heat so why it melts,
Not really. Snow is minute particles of ice loosely joined together, and when you pack it together hard, all the particles of ice come together and makes one big lump of ice. Another thing; If it was liquid, it would be called rain, not snow.
Vodka is the fastest liquid ice cube melter. It also won't freeze until it is minus sixty degree out side.
At room temperature and up to around 100o F, Vaseline is a semi-solid, or quasi-solid, which has characteristics of both a solid and a liquid. It melts at around 100o F, and behaves only as a liquid.
Steam condences into water, water freezes in to ice, ice melts into water, water boils to steam
Melting and boiling (vaporization) absorb energy, freezing and condensing release energy.
released
It melts. Energy is absorbed.
it melts
The thermal energy of the water increases as it melts, changing from a solid (ice) to liquid water. For a solid to melt, it is necessary for it to absorb energy from its surroundings.

When ice melts it is called a physical endothermic change.
When matter melts, the energy is used to break the bonds holding the solid structure together, causing the particles to move more freely. This increase in energy leads to a change in state from solid to liquid, without any increase in temperature. The energy required for melting is known as the heat of fusion.
When ice melts, the particles of water absorb heat energy from their surroundings. This energy causes the particles to gain kinetic energy, allowing them to break free from their rigid structure and transition from a solid to a liquid state.
The solid absorbs energy from the surroundings, causing the molecules to move around and no longer be in a tight structure (solid) but moving around fairly easy (liquid).
When it melts it is a liquid![:
