No, whole cloves are not broken up to help release the eugenol during distillation.
Steam distillation:
Live steam is used in the co-distillation technique of steam distillation to separate mixture components.
It works well to extract essential oil constituents with high boiling points, such as those with boiling points of 200°C. However, the oil vapors themselves are warmer—around 100°C—helping to maintain the compounds' structural integrity.
It enables distillation to be carried out at lower temperatures than the boiling points of the constituent parts.
The high-boiling essential oils are vaporized by steam, and after passing through a cooling system, the hot vapors that were formed from them condense back into a liquid along with water.
A two-phase distillate, consisting of a water layer and an oil layer, is created because the oils are immiscible in water.

It knows that when water evaporates, it carries heat energy away with it. So your body puts some water out on your skin, and hopes that it will evaporate. We call that "perspiring" or "sweating".
