Forms of matter that are not composed of molecules and are organized by different forces can also be considered different states of matter. Superfluids (like Fermionic condensate) and the quark–gluon plasma are examples. In a chemical equation, the state of matter of the chemicals may be shown as (s) for solid, (l) for liquid, and (g) for gas.
Matter organizes into various phases or states of matter depending on its constituents and external factors like pressure and temperature. Except at extreme temperatures and pressures, atoms form the three classical states of matter: solid , liquid and gas .
A head of state is the public persona of a sovereign state. [1] The name given to the office of head of state depends on the country's form of government and any separation of powers; the powers of the office in each country range from being also the head of government to being little more than a ceremonial figurehead.
Even in the presence of one or more Heads of State, certain occasions are governed by specific protocol, e.g. military. Thus in many cases precedence is given to monarchs over republican heads of state, mostly in monarchies; in some nations, the Pope (himself a monarchical head of state) ranks above secular heads of state, especially in Roman ...
A common simplified definition of a republic is a government where the head of state is not a monarch. [ 37 ] [ 38 ] Montesquieu included both democracies , where all the people have a share in rule, and aristocracies or oligarchies , where only some of the people rule, as republican forms of government.
Equilibrium thermodynamics is the study of transfers of matter and energy in systems or bodies that, by agencies in their surroundings, can be driven from one state of thermodynamic equilibrium to another. The term 'thermodynamic equilibrium' indicates a state of balance, in which all macroscopic flows are zero; in the case of the simplest ...
Most directly, it can be identified by a suitable set of state variables. Less directly, it can be described by a suitable set of quantities that includes state variables and state functions. The primary or original identification of the thermodynamic state of a body of matter is by directly measurable ordinary physical quantities.
The head of state is typically elected or nominated by representatives. In a democratic state, power is wielded by the people of the state, typically through a mixture of elected representatives and direct voting, but in theory could happen purely by Direct democracy without elected representatives
