Solve for the given letter from the indicated example of this section.

For the formula in Example 5, solve for β.

Data from Example 5

The volume V (in mm³) of a copper sphere changes with the temperature T (in °C) according to V = V₀ + V₀ βT,   where V₀ is the volume at 0°C. For a given sphere, V₀ = 6715mm³ and β = 5.10 ×10⁻⁵/°C. Evaluate T for V = 6908mm3. We first solve for T and then substitute the given values.

Now substituting, we have

V = V + VBT V - V = VBT T V - Vo Vo
