| critical period | <psychology> A specific stage in animal and human development during which certain types of behaviour normally are shaped and molded for life. (12 Dec 1998) |

| critical pH | The pH range, about 5.5, at which saliva ceases to be saturated with respect to calcium and phosphate, and below which tooth mineral will dissolve. (05 Mar 2000) |
| critical point | A point at which two phases become identical; thus, at a given critical temperature and critical pressure, the liquid and gaseous state of a particular substance can no longer be differentiated. (05 Mar 2000) |
| critical point drying | <procedure> A method for preparing specimens for the scanning electron microscope that avoids the problems of shrinkage caused by normal drying procedures. Water in the specimen is replaced by an intermediate fluid, for example liquid carbon dioxide, avoiding setting up a liquid/gas interface and then the second fluid is allowed to vaporise by raising the temperature above the critical point, the temperature at which the liquid state no longer occurs. (18 Nov 1997) |
| critical pressure | The minimum pressure required to liquefy a gas at the critical temperature. (05 Mar 2000) |
| critical rate | A heart rate at which aberration or incomplete block will occur; a result of shortening of cycle length so that it barely includes the refractory period. (05 Mar 2000) |
| critical temperature | The temperature of a gas above which it is no longer possible by use of any pressure, however great, to convert it into a liquid. (05 Mar 2000) |
| critical velocity | <biology> The maximum speed a device or organism can sustain over a specified distance or length of time, or the maximum velocity against which device or organism can sustain a position over a specified length of time. <marine biology> Velocity through which a fish will not swim, creating a velocity barrier. (09 Oct 1997) |
| critical pressure |
The critical temperature of a material is the temperature above which distinct liquid and gas phases do not exist. As the critical temperature is approached, the properties of the gas and liquid phases become the same. Above the critical temperature, there is only one phase. The critical pressure is the vapor pressure at the critical temperature. The critical molar volume is the volume of one mole of material at the critical temperature and pressure. ...
