The phase change of a liquid to a solid is referred to as either solidification or freezing. When the temperature of a substance is lowered below the substance's freezing point, the substance goes through a phase change from a liquid to a solid.Know More
The terms solidification and freezing are used interchangeably. This process occurs when heat is taken away from a liquid substance past its freezing point. The substance then crystallizes and forms stronger bonds between molecules, giving it a rigid structure.
Every known liquid freezes into a solid when enough heat is taken away except for liquid helium, which stays liquid even when the temperature is absolute zero. The opposite of freezing or solidification is called melting.Learn more about States of Matter
Heat provides the energy needed to change a solid into a liquid. Heat energy is added to break the bonds between molecules in a solid. The amount of heat needed to cause a solid to turn to a liquid is called the melting point.Full Answer >
Sublimation is a phase change process in which a substance is taken directly from a solid to a gaseous state without becoming a liquid in between. One common example of sublimation is dry ice.Full Answer >
Pressure raises the temperature at which a given type of matter changes states, such as going from solid to liquid or liquid to gas. For example, water boils at 212 degrees Fahrenheit at sea level. At higher altitudes, the pressure from the atmosphere decreases and therefore lowers the boiling point.Full Answer >
Fire is not a solid, a liquid or a gas because it is not a state of matter. Instead, it is a process of rapid oxidation in which heat and light are released. Fire can be used for both creative and destructive purposes.Full Answer >
