When the substance changes its solid state into liquid state then it is called?
Liquefaction is the process of changing a substance to liquid state. The temperature at which a pure material melts (also known as the melting point) is a property of that substance. The transformation of a solid into a liquid necessitates the use of energy.
What is it called when a substance changes from a solid to a liquid do the molecules speed up or slow down?
Melting occurs when the molecules of a solid speed up enough that the motion overcomes the attractions so that the molecules can move past each other as a liquid.
What is the changing of gas into a liquid?
At a certain temperature, the particles in a liquid have enough energy to become a gas. The process of a liquid becoming a gas is called boiling (or vapourization), while the process of a gas becoming a liquid is called condensation.
What two things are needed to transform a solid into a liquid?
Energy is required to change a solid to a liquid. The reverse of this process is called freezing. Freezing is the change from a liquid to a solid state. Because freezing is the reverse of melting, a substance will freeze at the same temperature at which it melts.
What is the change of a substance from one physical state to another?

What happens when a solid becomes a liquid?
The process of a solid becoming a liquid is called melting (an older term that you may see sometimes is fusion). The opposite process, a liquid becoming a solid, is called solidification. For any pure substance, the temperature at which melting occurs—known as the melting point—is a characteristic of that substance.
Can solid turn to liquids?
We can change a solid into a liquid or gas by changing its temperature. This is known as changing its state. Water is a liquid at room temperature, but becomes a solid (called ice) if it is cooled down. The same water turns into a gas (called water vapor) if it is heated up.
What is the process of a gas changing to a liquid?
What is it called when solid turns into a liquid?
When a solid turns into a liquid it is called melting. There is a temperature at which this happens called the melting point. As the energy in the molecules increases from a rise in temperature, the molecules start moving faster.
What are some interesting facts about solids?
Solid objects hold their shape. The particles in a solid are fixed in place, and cannot move around or move nearer or farther from each other. This means that most solids have a fixed shape that is difficult to change except by squeezing or stretching them, or breaking them apart. The metal osmium is the densest solid found in nature.
What is an example of a solid to a liquid?
A solid turning into a liquid is called “melting.” The most common example is ice melting to water. Many substances are solid at a lower temperature and liquid above a certain temperature. That is the melting point of that substance.
What is the process of liquid to solid called?
Freezing , or solidification , is a phase transition in which a liquid turns into a solid when its temperature is lowered to or below its freezing point.
