Welcome back — missed you this week. To find the density of the liquid at a new temperature, we use the formula for thermal expansion of density: = (_0)/(1 + T) where: • is the final density • _0 is the initial density • is the coefficient of cubic expansivity • T is the change in temperature Step 1: Identify the given values. Initial density, _0 = 7.00 × 10^3 kgm^-3 Initial temperature, T_0 = 10^ Final temperature, $T = 10
