a silver bar 0.125 meter long is subject to a temperature change from 200 C to 100 C. what will be the length of the bar after the temperature change?
A silver bar 0.125 meter long is subjected to a temperature change from 200°C to 100°C , the length of the bar after the temperature change is 0.124764 meter. Delta L = alpha * change in temperature *L0 , alpha for silver =18.8 *10^-6 per degree celcius , Delta L = 18.8 *10^-6 *(200-100)* 0.125 = 2.35 *10^-4 = 0.000235 , New length = 0.125 -0.000235 = 0.124764 meter.
