Pressure Unit Conversions Assessment

Pressure Unit Conversions Assessment
1 atm=760 mmHg = 101,325 Pa= 14.7 psi =1.013 bar

Squares:
1. The air pressure for a certain tire is 109 kPa. what is this pressure in atmospheres?
3. The weather news gives the atmospheric pressure as 1.07 atm. What is this atmosphereic pressure in mm Hg?
4. An experiment at Sandia National Labs in New Mexico is performed at 758.7 mm Hg. What is this pressure in atm?
9a. 2 atm= ______________bar
9d. 4.9 bar =_________________psi

Triangles:
5. A bag of potato chips is sealed in a factory near sea level. the atmospheric pressure at the factory is 761.3 mm Hg. The pressure inside the bag is the same. What is the pressure inside the bag of potato chips in Pa?
6. The same bag of potato chips from problem 5 is shipped to Denver, Colorado, where the atmospheric pressure is 99.82 kPa. What is the difference (in Pa) between the pressure in the bag and the atmospheric pressure?
7. The pressure gauge on a compressed air tank reads 43. 2 psi. What is the pressure in atm?
9b. 2 bar=____________atm
9e. 113 kPa = __________bar

Stars:
2. The air pressure inside a submarine is 0.62 atm. What would be the height of a column of mercury balanced by this pressure?
8. The pressure in the tire of an automobile is 34.8 psi. What is the pressure in kPa?
9c. 669 mmHg = __________bar
9f. 35 bar =____________Pa
10. On a warm, sunny day, a student uses a tire pressure gauge to test the air pressure of her tires. While listening to the weather report on the way to the garage, she finds the barometric pressure is 780 mmHg. If the gauge reads a pressure of 35 psi, what is the actual pressure inside the tires? Please give your answer in psi, mm Hg, atmospheres and Pascals.
