- The barometric pressure is about half the sea-level value of 760 mm Hg at an altitude of 4,000-5,000 feet 9,000-10,000 feet 14,000-15000 feet 18,000-19,000 feetSerena uses a 25-mL buret in order to transfer approximately 20 mL of a liquid into a beaker. In her notebook, she determines the transferred volume of liquid is 19.73 mL. Use the dropdown menus to fill in the blank according to Serena's data: The digit in the tenths, tens, ones, hundredths place is considered to be an estimated value. The words in bold are the answer choices and I need help figuring which one it is.A 40.0L balloon is filled with air at sea level (1.00 atm, 25.0°C). It is tied to a rock and thrown in a cold body of water, and it sinks to the point where the temperature is 4.0°C and the pressure is 11.0 atm. What will its new volume be?
