Answer 1

Answer:

Liquid air is air that has been cooled to very low temperatures (cryogenic temperatures), so that it has condensed into a pale blue mobile liquid.

Answer 2

Answer:

Liquid Air: Liquid air is air that has been cooled to very low temperatures, so that it has condensed into a pale blue mobile liquid. To thermally insulate it from room temperature, it is stored in specialized containers. Liquid air can absorb heat rapidly and revert to its gaseous state.

Hiw it is obtained: The most common process for the preparation of liquid air is the two-column Hampson–Linde cycle using the Joule–Thomson effect. Air is fed at high pressure (>75 atm (7,600 kPa; 1,100 psi)) into the lower column, in which it is separated into pure nitrogen and oxygen-rich liquid.
