Question

A cube of solid lead has a volume of 1.02 m³ at 20.3^oC. What temperature change is required to produce a 119 cm³ increase in the volume of the cube? Do not enter units.

Answer 1

The change in the volume V of a solid with change in temperature can be written as;

  

Here is the coefficient of volume expansion. For solid lead, = 29 10^-6 K^-1. Therefore final temperature T_f will be;
