What is critical temperature explain?
The critical temperature of a substance is the temperature at and above which vapor of the substance cannot be liquefied, no matter how much pressure is applied.
What is critical temperature give an example?
The critical pressure of a substance is the pressure that must be applied in order to liquefy that substance at its critical temperature. For example, 217.7 atmospheres of pressure must be applied to water in order to liquefy it at its critical temperature (which is 647.09 Kelvin).
What is critical phenomenon in chemistry?
The phenomenon of a smooth merging of a gas into its liquid state under a critical state or critical point is referred to as ‘critical phenomenon’. The volume occupied by one mole of a gas at its critical temperature and critical pressure is called the critical volume and is denoted by Vc.
What is a critical temperature in biology?
upper critical temperature (critical thermal maximum) The maximum body temperature that can be tolerated by an organism. When body temperature exceeds the upper critical point, cellular components and process become disrupted, and the organism eventually dies.
What is critical temperature in solid state physics?
Critical Temperature T c

What is critical temperature formula?
Tc=27Rb8a.
What is meant by critical phenomena in liquids?
Critical phenomena The unusual physical properties displayed by substances near their critical points. However, if the enclosed water is at a density close to 322.2 kg · m-3, rather extraordinary phenomena will be observed.
What is lower critical temperature biology?
-Lower critical temperature (LCT) is defined as the temperature below which a resting animal must increase its metabolic rate from the basal level (i.e., the SMR) to meet environmental demands for heat.
What is the definition of a lower critical temperature Mcq?
Explanation: The lower critical solution temperature is the lowest temperature at which two components are insoluble and attains equilibrium.
What are critical constants explain?
Definition of critical constant : the critical temperature, critical pressure, or critical density of any one substance —usually used in plural.
