Question

what length of water column is equivalent to 0.76 meter of Mercury column ?

Answer 1

Formation of dissolved gaseous mercury (DGM) was measured in lake water incubated at midday in Teflon bottles. DGM production was photoinduced as transparent bottles yielded DGM concentrations that were 2.4-9 times higher than dark controls. These results provide the first experimental evidence obtained in the field of a direct link between solar radiation and DGM production. A positive relationship was found between photoinduced DGM production at different times of the year and incident radiation. Removal of UVB light or …

Answer 2

Explanation:

given :- height of mercury column h1 = 0.76

Let h2 be the height of water column which will produce same pressure as height h1 (=0.76m) of mercury column .

Then h1p1g = h2p2g

so, h2 = h1p1 / p2 = 0.76 × 13.6 = *10.34m*

*Assumption* : The density of mercury is 13.6 times the density of water I.e p1= 13.6p2
