HELP How is pressure measured?

1. Which statement best describes air pressure at high altitudes? (Points: 3)

Air pressure decreases as altitude increases.



Air pressure increases as altitude increases.



Air pressure does not change as altitude increases.



It is impossible to accurately measure air pressure at high altitudes.







2. If volume decreases in a gas, what happens to pressure? (Points: 3)

Pressure stays the same.



Pressure increases and then decreases.



Pressure increases.



Pressure decreases.







3. If temperature increases, what happens to pressure? (Points: 3)

Pressure stays the same.

Pressure decreases.

Pressure increases.





4. Which of the following best describes the gas in a scuba tank? (Points: 3)

The gas is compressed.



The molecules of gas are moving slowly.



The gas barely fills its container.







5. If you place a balloon in the freezer, it will __________. (Points: 3)

stay the same size because there is no relationship between volume and temperature



expand because volume is inversely proportional to temperature



deflate because volume is directly proportional to temperature



deflate because volume is inversely proportional to temperature







6. What happens when you compress a gas? (Points: 3)

You decrease its pressure.

You increase its volume.

You increase its density.





7. In the Gas Laws lab, you changed temperature to change __________. (Points: 3)

gravity



volume



pressure







8. Which of the following is the most accurate statement concerning volume and pressure of a gas? (Points: 3)

Volume of a gas is always greater than pressure of that gas in any container.

Volume of a gas is directly proportional to pressure of that gas in any container.

Volume of a gas is inversely proportional to pressure of that gas in any container.

Volume of a gas is equal to pressure of that gas in any container.





9. What is the temperature of a gas in which the atoms are moving very, very slowly? (Points: 3)

cold



hot



room temperature







10. Which of the following measures atmospheric pressure? (Points: 3)

a thermometer



a ballast tank



a barometer







11. How is pressure measured? (Points: 3)

Pressure is measured as force per inch.

Pressure is measured as force per gram.

Pressure is measured as force per unit area.

Pressure is measured as force divided by mass.





12. Which example best demonstrates the relationship between temperature and pressure? (Points: 3)

bubbles on a pizza popping when they are cut



bubbles forming in dough when it is heated



evaporating water



melting ice







13. When a gas is compressed, the molecules are pushed closer together causing the gas to __________. (Points: 3)

drop in temperature

maintain its temperature

rise in temperature





14. Carbon dioxide being released from a fire extinguisher a good example of how volume __________. (Points: 3)

decreases when pressure decreases



decreases when pressure increases



increases when pressure decreases



increases when pressure increases







15. Which of the following statements describes how a heat pump works? (Points: 3)

A heat pump decompresses gas to warm and cool air.



A heat pump compresses gas to warm and cool air.



A heat pump decompresses gas to warm air and compresses gas to cool air.



A heat pump compresses gas to warm air and decompresses gas to cool air.HELP How is pressure measured?
What? Did you lose your textbook or something? If not, I would say the EXACT same thing as Brad J. I'll give you the first five because I sympathize your hate for homework(But I do not condone laziness!!!) and because I simply want %26quot;Best Answer%26quot;.





1. Air pressure decreases as altitude increases.

2. Pressure increases(NOTE: If Temp. remains constant).

3. Pressure increases(NOTE: If volume remains constant).

4. The gas is compressed.

5. deflate because volume is directly proportional to temperature

I did them al but I've decided not to write them out. There is something unsavory about this sort of mass posting, when there hasn't even been an attempt to read the questions before the cut and paste.
