Respuesta :

- Due to their electron affinities.

- Due to larger cohesive force of attraction between dews and metal than between dews and rubber(non - metals)

This question is based on the comparison of 2 surfaces and their behavior in specific cases.

Now, the rubber parts are non-metals and non-metals have a greater electron affinity than metals due to the fact that non-metals usually have more valence electrons than metals do.

Their higher electron affinity means that they easily attract more electrons than metals and thus, the dew will reside on metals faster.

Lastly, the cohesive force of attraction between metals is far more than that of between non - metals and dews and as a result the dew will form faster on metals than non - metals like rubber.
