To reduce the temperature to low water until saturated. And can not hold any more water vapor. Steam is condensed into water droplets change state faster.
To reduce the temperature of the steam, lowered to saturated and unable to hold more water vapor. Water vapour condenses, thus changing the status to drip faster.
To reduce it down to a low temperature, steam, saturated steam and is not able to store more than this so steam condensation condensation Change Status to speed up.
