After completing a deep-sea dive, a diver climbs onto the deck of a boat. The wind is blowing strongly, and the diver is wet with seawater.
Use ideas about particles to explain why the evaporation of seawater from the diver's skin and wetsuit cools them down.
To prevent their core temperature from falling too rapidly in the cold wind, the diver immediately wraps themselves in a specialized windproof deck coat which has a shiny, metallic-lined inner surface.
Suggest why the diver might cool down dangerously fast on the deck of the boat if they do not put on the coat.
Explain how the windproof, metallic-lined coat reduces heat loss from the diver's body.
