23. The coefficient linear expansion of brass is 19 x 104 °C1. What will be the value of co-efficient ofvolume expansion of the brass?1) 15x10° C" 2) 32x10-6 сс"3) 57x10-6 ос"4) 45x106 ос"

Answer»

Coefficient of volume expansion = coefficient of linear expansion * 3= 19*(10^-6)*3= 57*(10^-6) °C-¹
