参考答案:
A thermometer in the direct sunlight would gain
thermal energy (and thus show a higher temperature) due to receiving radiation
directly from the Sun. The emissivity of
air is small, and so it does not gain as much energy from the Sun as the
mercury and glass do. The thermometer is
to reach its equilibrium temperature by heat transfer with the air, in order to
measure the air temperature.
