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.Know More
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
Although most substances can occur in any of the four stages of matter (solid, liquid, gas or plasma), the factors that determine the substance's state are its chemical structure and the temperature. When the temperature increases, it excites the individual molecules, causing them to move around faster and become further apart from one another.Full Answer >
The changing of a liquid into a vapor is known as evaporation. This process requires a certain level of energy, often in the form of heat, to take place.Full Answer >
Henry's law, formulated by chemist William Henry in 1803, states, "at a constant temperature, the amount of a given gas that dissolves in a liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid." The solubility of a gas in a liquid depends directly on the partial pressure of the gas over the liquid.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 >
