Aleena visited a Natural Gas Compressing unit and found that the gas can be liquefied under specific conditions of temperature and pressure. While sharing her experience with friends she got confused. Help her to identify the correct set of conditions. (a) Low temperature, low pressure
(b) High temperature, lowpressure
(c) Low temperature, highpressure​

(c) Low temperature, high pressure

Explanation:

Liquefaction of a gas means the conversion of the gas to liquid. To convert a gas to liquid, we have to look a bit at the statements of the kinetic theory of gases.

Gases show ideal behavior within the range of high temperature and low pressure. Under these conditions, minimum intermolecular interactions occur between gas molecules.

However, as the temperature is deceased and pressure in increased, intermolecular interactions become significant and the gas begins to liquefy.

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b
