Chapter 3: Problem 19

Critical temperature means above this temperature at any pressure, any gas can be (a) liquefied (b) not liquefied (c) both statements are correct (d) Solified

Short Answer

Expert verified
The correct answer is (b) not liquefied.

Step by step solution

01

Understanding Critical Temperature

Critical temperature is the temperature beyond which a gas cannot be liquefied, no matter how much pressure is applied. In other words, above this temperature, gas particles have too much kinetic energy to be forced into a liquid state by pressure.
02

Evaluating the Statements

Looking at the given options, we can evaluate each with respect to the defined concept of critical temperature. (a) refers to gases being 'liquefied' - which is incorrect as gases can't be liquefied above the critical temperature. (b) states that gases cannot be 'liquefied' - which is correct. (c) says 'both statements are correct' which still contains the incorrect statement (a), making it incorrect. (d) says 'solidified' which is not related to the concept of critical temperature as it involves changing to a solid phase, not a liquid one.
