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 is false that an ice cube melts when it's mechanical energy increases.
yes
The particles start moving, and it melts. After it melts, it can evaporate if it gets to hot. For example: an ice cube
IT slowly increases back to room temperature
it melts
The water level remains the same after the ice cube melts because the volume of the ice cube is already accounted for in the water level when it is frozen. When the ice melts, it simply changes state from solid to liquid without changing the overall volume in the glass.
When it melts it is a liquid![:
Okay, let's say you put ice next to some coffee. Thermal energy travels from the coffee into the ice. So when the thermal energy store in the coffee decreases the temperature decreases and the ice cube increases and melts. I hope I helped
As an ice cube melts, its mass remains constant because the matter is conserved. However, the volume of the ice cube increases as it turns into liquid water due to the decreased molecular organization in the liquid state compared to the solid state.
The ice cube (solid) particles are compact tightly together. Yet, when the temperature of the ice cube increases then the particles become more active and begin to move apart except they are still attracted to one another.
a ice cube melts when it heats up
No, it becomes a liquid when it melts.
