Question

Identifying a constant of variation question

R= ?

Answer 1

Pressure and Volume are inversely related as:


`P= (R)/(V)`

We can also write it as:


`PV=R`

R is the constant of proportionality. Using the first row of given table, we can write:


`2(4.155)=R \\ \\ R=8.31`

Thus, the value of R, the universal gas constant is 8.31
