A steel scale measures the length of a copper rod as `l_(0)` when both are at `20^(@)C`, which is the calibration temperature for the scale . The scale reading when both are at `40^(@)C`, is :-

A steel scale measures the length of a copper wire as 80.0 cm when both area at 20^(@)C (the calibration temperature for scale). What would be the scale read for the length of the wire when both are at 40^(@)C ? (Given alpha_("steel") = 11 xx 10^(-6) per ^(@)C and alpha_("copper") = 17 xx 10^(-6) per^(@)C )

A steel tape measures that length of a copper rod as 90.0 cm when both are at 10^(@)C , the calibration temperature, for the tape. What would the tape read for the length of the rod when both are at 30^(@)C . Given alpha_("steel")=1.2xx10^(-5)" per".^(@)Cand alpha_(Cu)=1.7xx10^(-5)per .^(@)C

Which is NOT a scale of temperature measurements?

At what temperature will both celsius and fahrenheit scales read the same value?
