Step 1:
I'll solve this problem step by step, following the specified LaTeX formatting guidelines:

Step 2:
: Understand the Condensation Process

Condensation occurs when water vapor (steam) cools down and changes from a gaseous state to a liquid state. This happens at a specific temperature known as the dew point or condensation point.

Step 3:
: Identify the Condensation Temperature

At standard atmospheric pressure (1 atm), water vapor begins to condense into liquid water droplets at $$100^\circ\mathrm{C}$$ (212°F).
This is the boiling point of water, which is also the temperature at which water vapor starts to form liquid droplets.

Step 4:
: Consider Atmospheric Pressure

The exact condensation temperature can vary slightly depending on atmospheric pressure. At different pressures, the condensation point may change: - Lower pressure: Condensation occurs at a lower temperature - Higher pressure: Condensation occurs at a higher temperature

Step 5:
: Practical Observation

In everyday conditions (at sea level), when steam cools to $$100^\circ\mathrm{C}$$, it will begin to form water droplets.

Final Answer

Steam forms droplets of water at 100^\circ\mathrm{C} (212°F) under standard atmospheric pressure.
