Question

The two specific heat capacities of a gas measured as `C_p = (12.28 +- 0.2)` units and `(C_(upsilon) = (3.97 +-0.3)` units. Find the value of gas constant R.

Answer 1

Here, `C_p = (12.28 +- 0.2)units`
`C_(upsilon) = (3.97 +-0.3)units, R = ?`
As `R = C_p - C_(upsilon)`
`:. R = 12.28 - 3.97 = 8.31units`
`DeltaR = +-(DeltaC_p + DeltaC_(upsilon) = +-(0.2 + 0.3) =+-0.5units`
`Here, R = (8.31 +- 0.5)units`
