antoine equation meaning in Hindi

Examples

1. Commonly used are simple extensions of the Antoine equation ( see below ) and the equations of DIPPR or Wagner.
2. The Antoine equation is a mathematical expression of the relation between the vapor pressure and the temperature of pure liquid or solid substances.
3. The Antoine equation is among the least complex of these, having only three parameters ( A, B, and C ).
4. The Antoine equation has poor accuracy with any single parameter set when used from a compound's melting point to its critical temperature.
5. So the simple unattributed formula and the Antoine equation are reasonably accurate at 100 �C, but quite poor for lower temperatures above freezing.
6. According to a dew point calculator at this site ( as an alternative, one may use the Antoine equation to obtain an approximate value ), that partial pressure results in the local dew point of about 0.86 �C; in other words, the new local dew point is about equal to the new local temperature.
7. Ethyl cyanoacetate is a colorless liquid, it boils at atmospheric pressure at 209 �C . The vapor pressure follows the Antoine equation log 10 ( P ) = A " ( B / ( T + C ) ) ( P in bar, T in K ) with A = 7.46724, B = 3693.663 and C = 16.138 in the temperature range from 341 to 479 K In solid phase, two polymorphic forms can occur.
