When Dylan got off from an air-conditioned bus, the lens of his spectacles became blurred. What caused this to happen?
Warmer water vapour from the air-conditioned bus came into contact with a cooler outer surface of his spectacles' lens, lost heat and condensed into water droplets.
Warmer water vapour from the surrounding air came into contact with a cooler outer surface of his spectacles' lens, gained heat and condensed into water droplets.
Cooler water vapour from the air-conditioned bus came into contact with a warmer outer surface of his spectacles' lens, gained heat and condensed into water droplets.
Warmer water vapour from the surrounding air came into contact with a cooler outer surface of his spectacles' lens, lost heat and condensed into water droplets.
