A glass rod when measured with a zinc scale, both being at `30^(@)C`, appears to be of length `100`cm . If the scale shows correct reading at `0^(@)C`, then the true length of glass rod at `30^(@)C` and `0^(@)C` are :-
(`alpha_("glass") = 8 xx 10^(-6)"^(@)C ^(-1), alpha_("zinc") = 26 xx 10^(-6) K^(-1)`)
