Question

The temperature below which a gas can be liquified by increasing its pressure is known as:

• A. zero
• B. neutral temperature
• C. critical temperature
• D. boyle temperature

Answer 1

Answer: (C)

critical temperature

Zero: absolute temperature
Neutral temperature: The temperature of the hot junction of a thermocouple at which the electromotive force of the thermocouple attains its maximum value when the cold junction is maintained at a constant temperature of 0°C.

Critical Temperature: The temperature below which a gas can be liquified by increasing its pressure.

Boyle temperature: The temperature above which the liquid evaporates at normal pressure is called Boyle temperature

$\therefore$ Critical temperature is the correct answer.
