However it shows some difference on the actual value of the measurement l = lo (1 + T)
Copper: l= 88(1+16.6x10-6x30.3) = 88.044mm lo=88mm | y=16.6x10-6 | ∆T=30.3◦C | l=? |

Aluminium lo=79mm | y=25 x 10-6/ºC | ∆T=36 ºC | l=? | l = lo (1 + ∆ T) l=79(1+25 x 10-6/ºC x 36 ºC =79.07mm

Brass lo=88mm | y=18.7 x 10-6/ºC | ∆T=47.9 ºC | l=? | l = lo (1 + ∆ T) l=88(1+18.7 x 10-6/ºC x47.9 ºC) =88.07mm

Iron lo=88mm | y= 12x 10-6/ºC | ∆T=? | l=88.1 |
∆T=lloy)-1 = 88.1∕88x12x 10-6/ºC -1

Overall, the experiment succeeded that the metals show the theoretical properties. Differences existed in the mathematical calculation of the actual length. These differences, however, it can be accounted for by experimental error; more over there are uncertainty on purity of the
