When can liquid and gas be distinguished from each other?

Options

  1. AAt any temperature
  2. BWhen the fluid is below its critical temperature and pressure
  3. CWhen the fluid is above its critical temperature and pressure
  4. DWhen the fluid is in a vacuum

Correct answer

B. When the fluid is below its critical temperature and pressure

Step-by-step solution

Liquid and gas can be distinguished from each other when the fluid is below its critical temperature, and its pressure and volume lie under the dome, where liquid and gas are in equilibrium.
