Molecular formula :
nature : hot and cold objects of a measure. Temperature is the most basic thermodynamic variable one. The concept of temperature from the natural phenomena from summed up by law -- ZEROTH LAW OF THERMODYNAMICS. This principle can be expressed as follows : "If the system A and system B was thermal equilibrium (that is, when A and B did not contact the state changes), and B and C system was heat balance, the A and C were also on thermal balance. "Under this law, irrespective of A, B and C nature, the existence of a system of variables, it was in thermal equilibrium with each other in the system have the same value as the parameters on the temperature.
