Which of the following is not a possible effect of increasing carbon dioxide levels in the atmosphere?a. increase in water contamination and floodsb. ocean acidificationc. cutting down forestsd. reduction of cold-related deaths Please select the best answer from the choices providedABCD

b

Explanation:

The only option that is not an effect of increasing carbon dioxide levels in the atmosphere is cutting down forests.

An increasing level of carbon dioxide in the atmosphere causes ocean acidification due to the dissolution of the gas in the oceans. Carbon dioxide also causes global warming - an increase in the average global temperature due to the heat (from the sun) absorbing ability of the gas.

Global warming causes an increase in the level of seas and oceans as a result of the melting of glaciers and polar ice caps. The rise in sea levels causes flooding with associated loss of habitats and biodiversity.

The increase in global temperature also means that cold-related deaths will reduce.

Correct 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
