A glass flask has a volume of 500 ml at a temperature of 20 degrees celsius. The flask contains 492 ml of mercury at an equilibrium temperature of 20 degrees celsius. The temperature is raised until the mercury reaches the 500 ml 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, in degrees celsius is closest to:
