Explanation:
Expression for the coefficient of thermal expansion is as follows.
where, V = initial volume
= Final volume - initial volume
= (712.6 - 873.6)
= -161
Now, we will calculate the change in temperature as follows.
= Final temperature - Initial temperature
= (10 + 273) K - (70 + 273) K
= 283 K - 343 K
= -60 K
Substituting these values into the equation as follows.
= 0.00307
It is known that for non-ideal gases the value of alpha is 0.366% which is 0.00366 per Kelvin. As it is close to our result, hence the given sample of gas is a non-ideal gas.
