Solidification or freezing is the term used for the process in which a liquid becomes a solid. Freezing is an exothermic process that also is an example of a phase transition.Continue Reading
This process occurs when the temperature of the substance (the liquid) is lower than its freezing point.
The three states, or phases, of matter are gas, liquid and solid. A phase transition happens when matter in one phase changes to another phase due to a change in either temperature or pressure.
Besides solidification, other transition phases include melting, vaporization and condensation. An example of the opposite of freezing is melting. With melting, a solid turns to a liquid.Learn more about States of Matter
When a gas changes into a liquid, it undergoes a process called vaporization. When the state of matter of a substance changes, as it does during vaporization, it undergoes a phase change.Full Answer >
Salt water freezes slower than regular water because it has a lower freezing point. Unsalted water freezes when water molecules slow down from the removal of heat. The addition of salt creates more heat in the mixture, resulting in a lower freezing point.Full Answer >
How fast a liquid evaporates depends upon the type of liquid and the volume of the liquid, as well as how large the surface area upon which the liquid is spread. For example, if the same volume of water is placed in three petridishes of differing sizes, the water in the petridish with the largest diameter evaporates first.Full Answer >
Sound travels fastest through a solid, when compared to a liquid or a gas. The molecules in a solid are denser and can be disturbed at a more rapid pace.Full Answer >
