ConstantsPeriodic Table PartA To explorc the bottom oi a 15-m-deep lake, your friend Tam praposes to get a long garden hosa, put ore end on land and the other in his mouth for breathing underwater, and descend into the deths. Susan, who overhears the conversation·reacts with hamor and woms Ta that he wil not be able lo Why is Susan so wErried? The aressure at a degth af 15 m s 3.6x10 Pa. This is almast a.5ies greer than atmaspheric press pressure in the hosa wil be anly sightly higher han atrncepheric preeeure, because the deneity of air is so low. So Torn wil have grea! cilficully breathing in the low-pressure air when the large pressure of the water is pressing in on his chast Inhale when ha is at the lake bottom. The pressure at a deglh of 15 2.5x 10 Pa. This is almoet 2.5 ines grealer than atimospheric pressure. But he air pressure in the hose wil be only sighdy higher han almos neric pressure, because the: ens y o ar s so crw u Tor" wil have grea ul culty or ahng n ow ressure ar when ne lar e pressure 미 the: water spressrig n tri his chest. The pressure at a death or 15 ш is 3 × 10° Pa This is almost three times greater 1hen etmospheic pressure. But he ar pressure in Ihe hose wil be only algnty Ngher than atmoepheric preeeure, because the daneity of eir is so low. So Tom wil have greet cimcuity brestning nthe low-oreasure air when tne large pressure ot the weber is pressing in on his chest. The oreeaure at a death or 15 m s 2 × 1O? Pa This is almost two 1 mes greeter than atmospheric ressure. But he alr oreBsure in the hoee wil be only slightly higher then atmospheric pressue, because tha dansity of air is soow. So Tom wil have greet cifficuity areathing in tha low-arassure air when the lange prassure ot tha wahar is prassing in on his ches1 Submit

Answer 1

Ans The pressure at dep in water (n gkt The pressure in the hoos ill ncrease sl as the density f the air to the densitf the water is o louw when lowJ when Compared Since pressure on his chest 2.5%o. Pa. HewiA have frouble breathing in the ow- pressure air. 2nd option is Correct
