Ответ:
v = 18000/p
where
v = volume, in³
p = pressure, lb/in²
When the pressure is p = 900 lb/in², then the volume is
v = 18000/900 = 20 in³
20 in³
Ответ:
Volume of the gas is 20 cubic inches.
Step-by-step explanation:
Inverse proportion: Let x and y be two quantities are said to be inverse proportion or inversely proportional if one quantity increases at the same rate the other decreases.
or
⇒ where k is constant.
Since, it is given that the volume of gas is inversely propotional to its pressure.
Given the function:
......[1] ; where volume in cubic inches and pressure in pounds per square.
To find the volume in cubic inches.
The pressure (p) = 900 pounds per square inch.
Substitute the value of p in [1];
Therefore, the volume(v) = 20 cubic inches when the pressure is 900 pounds per square inch.
