Calculate the linear expansivity (α) of brass of length 120m that assumes anew length of 120.05m, when heated through a temperature of 100 degree Celsius.

Answer 1

If it's linear, it looks like (120.05-120)m/100°C = 0.0005 m/°C

Answer 2

calculate the alpha of brass long 120m that assume a new length of 120.05cm when heated through a temperature 100°c

Answer 3

0.42 x 10^-5 k^-1
