Which method can help prevent moisture accumulation on windows?

The correct choice focuses on maintaining a balance of temperature and relative humidity to reduce moisture accumulation on windows. Increasing the temperature of the window helps to lower the chances of condensation forming, as warmer air holds more moisture. When windows are warmer, the air immediately surrounding them can maintain a lower humidity level, thereby reducing the likelihood of moisture condensing on the glass.

Alternatively, decreasing the relative humidity (RH) of the house as a whole also minimizes the moisture in the air, resulting in drier conditions that are less conducive to condensation forming on windows. Both strategies effectively combat excessive moisture accumulation, which can lead to issues such as mold growth and damage to window frames.

Increasing humidity in the home would have the opposite effect, potentially leading to more condensation, while decreasing the temperature of the window could create conditions for more moisture accumulation. Installing more windows does not inherently address the moisture problem and could even allow for more areas where condensation may form, depending on the overall humidity and temperature dynamics of the space.
