A glass flask has a volume of 500 mL at a temperature of 20°C. The flask contains of mercury at
The temperature of the mercury and flask is raised until the mercury reaches the
reference mark. The coefficients of volume expansion of mercury and glass are 18 × 10-5 K-1 and 2.0 × 10-5 K-1, respectively. The temperature at which this occurs is closest to
