参考答案:
Snow, particularly at very low temperatures, has
a low thermal conductivity because it has many tiny air pockets trapped in its
structure – it might be described as “fluffy”.
Since this “fluffy” snow has a low thermal conductivity, the snow will
not conduct much heat away from an object covered in it.
