Question

Gases are different from solids and liquids. In a sample of gas, the molecules are far apart. The gas molecules also move around and collide with each other as well as with the walls of the container. These collisions generate pressure. The pressure of a gas can be measured in different units. One convenient unit of measure is called the atmosphere (atm) because it is based on atmospheric pressure. At sea level, the average pressure is 1 atm. As you get higher in altitude, the pressure steadily drops until you leave the atmosphere, where the pressure is very close to o atm. Convert 0.550 atm of pressure to its equivalent in millimeters of mercury. Express the pressure numerically in millimeters of mercury. View Available Hint(s) 0 AED O ? 0.550 atm mmHg Submit The table below shows the different commonly used units of measuring gas pressure. Use this table in the pressure unit conversions. Unit Abbreviation 1 atm equivalent atmosphere atm 1.00 atm (exact) millimeters of mercury mmHg 760 mmHg torr torr 760 torr inches of mercury in. Hg 29.9 in. Hg pounds per square 1b/in. Inch (psi) 14.7 lb/in. pascal Pa 101,325 Pa Part B The pressure in car tires is often measured in pounds per square inch (lb/in."), with the re 45 lb/in.. Suppose a tire has a pressure of 36.5 lb/in.?. Convert 36.5 lb/in. to its equ Express the pressure numerically in atmospheres.

Answer 1

from the table of units it is evident that, I at pressure = 760 mm Hg. now, 0.550 alm - (760x0.550) mm Hg. =.418 mm Hg Part B . & Holines? grease. * This expression can be obtained by torinou's Toriceny's experiment He obcered, when I meter =1000 mm tube was stonded in a container containing mercarry, In open space or in sea level, the mercury level was 160 mm) . So, it iѕ ел vа tо - то I am pressure: & please like, comment or do rating for better understanding and entrusisme
