The volume of a gas in cubic centimeters v,varies inversely with the pressure of the gas in liters per square centimeters,p when
scoundrel [369]

Answer:

The volume of the gas is 145.45\ cm^{3}

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form y*x=k or y=k/x

Let

v------> the volume of a gas in cubic centimeters

p-----> the pressure of the gas in liters per square centimeters

so

p*v=k

we have

v=16\ cm^{3}, p=20\ l/cm^{2}

substitute and solve for k

k=16*20=320

The equation is p*v=320

<em>Find  the volume of the gas when the pressure is 2.2 L/cm2</em>

so

For p=2.2\ l/cm^{2} Find the value of v

substitute in the equation

(2.2)*v=320

v=320/2.2=145.45\ cm^{3}
