Latent heat released during condensation affects droplet growth by
Answer: C
Correct answer: warming the droplet and reducing the vapour gradient
Condensation releases latent heat into the droplet, raising its temperature and therefore the saturation vapour pressure at its surface. That reduces the difference between the ambient vapour density and the surface value, which is what drives the diffusion, so the droplet grows more slowly than a purely diffusive calculation would predict. The effect is built into the growth equation as a thermodynamic term in the denominator.
