When there is impedance rather than resistance, the current flowing is out of phase with the voltage: the ratio of voltage:current depends on frequency. When there is impedance, the peaks and troughs of the voltage (red) and current (cyan) are out of phase. In this case, the current la...

Definition of Suspension What is a Suspension? A suspension is a heterogeneousmixturein which solute-like particles settle out of a solvent-like phase sometime after their introduction. We use the terms 'solute-like' and 'solvent-like' because we are dealing with a heterogeneous mixture, while ...

As biologicalsciencehas progressed, these primitive ideas about body chemistry have been replaced by more complex ideas and by contemporary studies of hormones, ...
2. In physical chemistry, any physically or chemically distinct, homogeneous, and mechanically separable part of a system. phase 0 in cardiac physiology, the phase representing the upstroke of the action potential, in which rapid depolarization occurs after the cell reaches or is driven to threshol...
In chemistry and physics, a phase is a physically distinctive form of matter, such as a solid, liquid, gas, or plasma.
Classically, it is admitted that three characteristic phases govern the biological activity of a drug in a living organism: the pharmaceutical phase, the pharmacokinetic phase, and the pharmacodynamic phase. About 6000 chemical entities can be used, in various pharmaceutical formulations, to treat ...
Sublimation is the transition from thesolidphase to thegasphase without passing through an intermediateliquidphase. Thisendothermicphase transition occurs attemperaturesandpressuresbelow thetriple point. The term "sublimation" only applies to physical changes of state and not to the transformation of a so...
Boiling Definition in Chemistry Chemistry Glossary Definition of Boiling Boilingis defined as a phase transition from theliquidstate to thegasstate, usually occurring when a liquid is heated to itsboiling point. At the boiling point, the vapor pressure of the liquid is the same as the external ...
