Question

A 10l cylinder has helium at 8atm and 27⁰c . The number of balloons of 5l each at 2atm and 27⁰c can be filled with the gas available from the cylinder is?​

Answer 1

Answer:

a + b = 8 and ab = 12

To Find- a^2 + b^2

Sol. a^2 + b^2

(a +b)^2 = a^2 + b^2 + 2 (ab)

(8)^2 = a^2 + b^2 + 2(12)

64 = a^2 + b^2 + 24

a^2 + b^2 = 64-24

Therefore a^2 + b^2 = 40
