If the average atmospheric pressure at sea level can support 10.34 m of vertical length of a water column, then its magnitude is about _______ Pa. Assume density of water = 1 g cm−3 and gravitational acceleration = 9.8 m s−2.   100000   100   1000   10000   Half-n-half Clue   3. The SI unit of pressure is   Joule   Watt   Newton   Pascal   Half-n-half Clue   4. Soap bubbles are spherical in shape because   air exerts equal pressure in all directions   soap film has a low surface tension   spherical shape has the highest ratio of surface area to volume   air trapped inside the bubble has low pressure   Half-n-half Clue   5. 6 bars = _______ millibars   6000   0.6   0.006   60   Half-n-half Clue   6.
