Answer:
1. When the butter is heated, the molecules begin to move and are able to slide past each other and become a liquid. When the liquid butter is cooled, the molecules slow down and reconnect to become a solid again.
2.The atoms in a liquid have more energy than the atoms in a solid. There is a special temperature for every substance called the melting point. When a solid reaches the temperature of its melting point, it can become a liquid. ... Liquid water freezes and becomes solid ice when the molecules lose energy.
3.We all know that the atoms of matters move fast whenever they are heated, making them transform to a new form. Like, if solid sugar is heated, it will become liquid through the process called caramelization. As well as, boiling water, if boiled to much, water will evaporate and it's gas already.
4.Heating a substance makes the molecules move faster. Cooling a substance makes the molecules move slower.
5.If we cool it down, it changes into a solid – ice. If we heat it up, it changes into a gas – steam. A particular material changes from being a solid to a liquid at a fixed temperature. This is its melting point.
6.in heating the properties are flexibility while cooling it turns harder like the ice
