Which statement about the volume and pressure of a gas is the most accurate?
o
Volume of a gas is equal to 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 always greater than pressure of that gas in any container.
©
Volume of a gas is inversely proportional to pressure of that gas in any container.

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

Explanation:

This is the explanation of Boyle's law which states that at constant temperature the Volume of a fixed mass of gas is inversely proportional to the pressure. This law is also known as Volume - pressure relationship

In application (in a gas container): if volume decreases, pressure decreases and vice versa

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
