Question

at a constant temperature the pressure of gas is inversly proportional to its volume if certain amount of gas occupies a volume of 30cc and exerts a pressure of 85g/cm2 then find the decrease in its pressure when the Same amount of gas occupies a volume of 75cc​

Answer 1

Answer:

Step-by-step explanation:

P is inversely proportional to volume

it means  

p1/p2  =  v2/v1  

Therefore ATQ

85/p2  =  75/30

p2=17

decrease in pressure = p1-p2

= 85-17         = 68
