The volume of a gas "V" varies inversely with the pressure "P" put on it. If the volume is 360cm³ under a pressure of 20 kgcm2
Sav [38]

Answer:

15 Kg cm²

Step-by-step explanation:

Given that V varies inversely with P then the equation relating them is

V = \frac{k}{P} ← k is the constant of variation

To find k use the condition

V = 360, P = 20, then

360 = \frac{k}{20} ( multiply both sides by 20 )

k = 7200

V = \frac{7200}{P} ← equation of variation

When V = 480, then

480 = \frac{7200}{P} ( multiply both sides by P )

480P = 7200 ( divide both sides by 480 )

P = 15
