Explanation:
The presence of residual solvent is a factor that affects the glass temperature of the polymer. This is because a residual solvent decreases the free volume in a polymer. All types of polymers have total occupied volume, which is composed of an occupied volume and a free volume. The free volume is the volume needed for the polymer chains to move around. Thus, if there is a big free volume in the polymer it will decrease the glass transition temperature and will both decrease and broaden the melting range of the crystals.
In a polymer with crystalline spherulites and the surrounding amorphous, will have a bigger surrounding amorphous with the presence of residual solvent. Which will decrease the melting range of the crystals. The structure found on the interior of the spherulites is pure crystalline polymer, so probably the residual solvent will not be inside them.
By state of matter I assume you mean solid, liquid, gas, in which case the answer would be C.
the behaviour of molecules:
- in a solid is low energy with limited activity where molecules only vibrate, cannot mould to shape of container
- in a liquid is with moderate energy, with molecules flowing over the top of one another, and thus can mould to the shape of the container
- in a gas is high energy with much activity, molecules "fly" around the container they are in and can be compressed
