A brass scale gives correct length at `0^(@)C`. If the temperature by `25^(@)C` and the length read by the scale is `10 cm`. Then the actual length will be

A steel scale gives correct reading at t_1^@C . When temperature changes to t_2^@C then

A steel scale gives correct reading at 10^(@)C . If the length of a rod is measured with the help of that scale at 30^(@)C then the measured length will be

A metal scale measures correct reading at 25^(@)C. A rod is measured to be 80 cm by the scale at 15^(@)C . What is the actual length of the rod? (alpha=15 times 10^(-6@)C^(-1))

At what temperature (in ^(@)C , the fahrenheit and celsius scale gives same reading?

A brass scale is correct at 20^@C . The length of a rod measured by it at 35^@C is 60 cm . What is the correct length of rod at that temperature ? ( alpha of brass = 18.9 xx 10^(-6) per^@C) .

A barometer with a brass scale correct at 0^(@)C reads 70 cm of mercury on a day when the air temperature is 40^(@)C . The correct reading at 0^(@)C is (Coefficient of real exapansion of mercury is 0.00018//^(@)C and coefficient of linear expansion of brass is 0.00018//^(@)C)

A Barometer with brass scale, which is correct at 0^(@)C , reads 75cm on a day when the air temperature is 20^(@)C . Calculate correct reading at 0^(@)C . (Coefficient of real expansion of mercury =0.00018//^(@)C and coefficient of linear expansion of brass =0.000189//^(@)C .)

A barometer with a brass scale correct at 0^(@)C reads 70 cm of mercury on a day when the air temperature is 40^(@)C . The correct reading at 0^(@)C is (Coefficient of real expansion of mercury is 0.00018//^(@)C and the coefficient of linear expansion of brass is 0.000018//^(@)C .
