CONDENSATION OF A PURE VAPOR
For a water-cooled condenser tube, the coolant-side heat transfer coefficient might typically be around 5 000 W/m 2 K. This is of similar magnitude to that found with film condensation of steam (5 000–15 000 W/m 2 K). For organic vapors, condensing-side heat transfer coefficients are lower typically by a factor of 5 or more.

Vapor Pressure and Water | U.S. Geological Survey
The vapor pressure of water is the pressure at which the gas phase is in equilibrium with the liquid phase. The high surface tension of water (water "sticks" to itself, so it doesn't "want to" evaporate) means water has a low vapor pressure. An explanation of vapor pressure. Sources/Usage: Public Domain.

Evaporation and the Water Cycle | U.S. Geological Survey
Evaporation occurs when energy (heat) forces the bonds that hold water molecules together to break. When you're boiling water on the stove, you're adding heat to liquid water. This added heat breaks the bonds, causing the water to shift from its liquid state to its gaseous state (water vapor), which we know as steam.

We needed to first determine the saturated vapor specific volume v g at 300°C. This value is 0.0216, which is much less than the specific volume v 3 of 0.2, thus placing state (3) well into the superheated region.
