A glass cylinder contains `m_0=100g` of mercury at a temperature of `t_0=0^@C`. When temperature becomes `t_1=20^@C` the cylinder contains `m_1=99.7g` of mercury The coefficient of volume expansion of mercury `gamma_(He)=18xx(10^(-5)//^(@)C` Assume that the temperature of the mercury is equal to that of the cylinder. The coefficient of linear expansion of glass `alpha` is
