The pressure of a gas p(v) varies inversely with the volume of gas v. the pressure of a gas measures 8kg/cm^2 when its volume is 40cm^3. which equation can be used to find the pressure of the gas when its volume is changed. a. p(v)=320vb. p(v)=320 over vc. p(v)=5vd. p(v)=5 over v

B

Step-by-step explanation:

Since p and v vary inversely then the equation relating them is

p = ← k is the constant of variation

to find k use the condition p = 8 when v = 40

k = pv = 8 × 40 = 320

⇒ p(v) = → B

B.

Step-by-step explanation:

We are given that

The pressure of gas p(v) varies inversely with the volume of gas v.

Pressure of gas measures=

Volume of gas=

We have to find the equation that can be used to find the pressure of the gas when its volume is changed.

According to question

p(v)

Where k=proportionality constant

Substitute the given values then, we get

Substitute the value of k then, we get

Hence,option B is true.
