Question

who can help me solve this with detail steps.

A cube of Brass measures 12.12 cm on a side a) Calculate its volume at room temperature. b) Calculate its size at liquid nitrogen temperature. c) Use the results of a) & b) to calculate the change in volume from room temperature to liquid nitrogen temperature. ) Use the volume espansion equation to calculate the change in volume from room temperature to liquid nitrogen temperature. e) Calculate the percentage difference between your answers in c) and d)

Explanation / Answer

Volume expansion co-efficient of brass: 57 x 10-6 /°C

Volume at RT = (12.12)^3 = 1780.4 cu. m

Change of temperature : (298-77) = 221 degrees

So, change is volume = 221*1780.4*57 x 10-6

= 22.43 cu cm

So volume

= 1780.4 -22.43 = 1758 degrees
