The volume, V of gas varies inversely with the Pressure, P on it. If the volume is 320 cm3 under pressure of 40 kg/cm2, what pre
ssure has to be applied to have a volume of 200 cm3?
1 answer:
Assuming that the gas behaves ideally.
Given the initial volume and pressure:
V1 = 320 cm3
P1 = 40 kg/cm2
and given the final volume:
V2 = 200 cm3
find the final pressure, P2:
PV = nRT; assume temperature and number of moles are constant
PV = constant
P1V1 = P2V2
Solve for P2:
(320 cm3) (40 kg/cm2) = (200 cm3) (P2)
P2 = 64 kg/cm2

Answer:
22 and 46
Step-by-step explanation:
let
one number is x
another is 2x+2
now 2x+2+x=68
or, 3x+2=68
3x=66
or x=66/3=22
so one number is 22 and another is (22X2+2)=46
Answer: m = -5
7.20+24.75=31.95
so 31.95 per student
31.95*350=11,182.50
This will cost the student body $11,182.50
