Liquids are similar to gases in that they both have
a. a definite volume.
b. no definite shape.
c. no definite volume.
d. particles that remain in contact with each other.

The correct answer is B. No definite shape

Explanation:

Gas and liquid are two different states of matter. In these states, particles move more freely than in a solid-state. Due to this characteristic, in both liquids and gases, there is not a defined shape; instead, liquids and gases adapt to the container or space where they are, although gases occupy all the space in a container. Besides this, they differ because gases do not have a defined volume as this can change through compression, while liquids have a defined volume. Thus, one similarity between gases and liquids is that they do not have a defined shape (option B).

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
