Question

Critical temperature of a gas is ______ its Boyle temperature.

• A. higher than
• B. equal to
• C. lower than
• D. no relation

Answer 1

The correct option is C lower than

Critical temperature of a gas is lower than its Boyle temperature .
Critical temperature is the highest temperature at which gaseous state starts condensing into liquid state.
Boyles temperature is the temperature at which real gases obey ideal gas equation over an appreciable pressure range.
Under ideal behavior of gases, the condensation should not occur.
Hence, at Critical temperature, the gas shows non ideal behavior. Thus this temperature is lower than Boyle's temperature.
