yes
It is false that an ice cube melts when it's mechanical energy increases.
An ice cube will melt when it is above the freezing point of water. At this point the individual molecules have enough energy to vibrate more causing the ice cube to melt.
it melts
When it melts it is a liquid![:
When an ice cube is heated, it absorbs heat energy and begins to melt, turning into liquid water. Continued heating will cause the water to further increase in temperature until it eventually turns into steam as it boils.
a ice cube melts when it heats up
No, it becomes a liquid when it melts.
on its own
water
No, not at all- the rate of melt of an ice-cube is entirely down to temeprature.
As the ice cube melts, the particles in the solid ice gain enough energy to overcome the forces holding them in a fixed position, allowing them to move more freely as a liquid. When the liquid water evaporates, the particles gain even more energy to break free from the liquid phase and become a gas.
