Question

for a fixed amount of gas at a constant temperature, the volume of the gas is inversely proportional to its pressure. the function $v = \frac{18,000}{p}$ relates the volume in cubic inches and pressure in pounds per square inch of a gas. what the volume when the pressure is 900 pounds per square inch? \bigcirc 0.05 in.\\(^3\\) \bigcirc 0.5 in.\\(^3\\) \bigcirc 20 in.\\(^3\\) \bigcirc 200 in.\\(^3\\)

Explanation:

Step1: Substitute pressure into formula

Substitute $P=900$ into $V=\frac{18,000}{P}$
$$V=\frac{18,000}{900}$$

Step2: Calculate the volume

Perform the division
$$V=20$$

Answer:

20 in.³
