A convention to propose amendments to the United States Constitution, also referred to as an Article V Convention, state convention, [1] or amendatory convention is one of two methods authorized by Article Five of the United States Constitution whereby amendments to the United States Constitution may be proposed: on the Application of two thirds of the State legislatures (that is, 34 of the 50 ...
In physics, a state of matter is one of the distinct forms in which matter can exist. Four states of matter are observable in everyday life: solid, liquid, gas, and plasma. Many intermediate states are known to exist, such as liquid crystal, and some states only exist under extreme conditions, such as Bose–Einstein condensates and Fermionic ...
In physics, chemistry, and other related fields like biology, a phase transition (or phase change) is the physical process of transition between one state of a medium and another. Commonly the term is used to refer to changes among the basic states of matter : solid , liquid , and gas , and in rare cases, plasma .
Constitutionof the United States. Article Five of the United States Constitution describes the procedure for altering the Constitution. Under Article Five, the process to alter the Constitution consists of proposing an amendment or amendments, and subsequent ratification. Amendments may be proposed either by the Congress with a two-thirds vote ...
v. t. e. In the physical sciences, a phase is a region of material that is chemically uniform, physically distinct, and (often) mechanically separable. In a system consisting of ice and water in a glass jar, the ice cubes are one phase, the water is a second phase, and the humid air is a third phase over the ice and water.
Missouri Compromise, 1820 federal statute enabling the admission of Missouri (a slave state) and Maine (a free state) into the Union. Toledo War, 1835–36 boundary dispute between Ohio and the adjoining Michigan Territory, which delayed Michigan's admission to the Union. Texas annexation, the 1845 incorporation of the Republic of Texas into ...
In common temperatures and pressures, atoms form the three classical states of matter: solid, liquid and gas. Complex molecules can also form various mesophases such as liquid crystals, which are intermediate between the liquid and solid phases. At high temperatures or strong electromagnetic fields atoms become ionized, forming plasma.
Equation of state. In physics and chemistry, an equation of state is a thermodynamic equation relating state variables, which describe the state of matter under a given set of physical conditions, such as pressure, volume, temperature, or internal energy. [1] Most modern equations of state are formulated in the Helmholtz free energy.
