**42. The column of mercury in a barometer (see Figure 11.11) has a height of 0.760 m when the pressure is one atmosphere and the temper- ature is 0.0 °C. Ignoring any change in the glass containing the mercury, what will be the height of the mercury column for the same one atmo- sphere of pressure when the temperature rises to 38.0 °C on a hot day? (Hint: The pressure in the barometer is given by Pressure = pgh, and the density p of the mercury changes when the temperature changes.)
