As the temperature increases and the amount of water vapor in a piece of air remains constant, what happens to the relative humidity?

<p style=";text-align:left;direction:ltr">Arab Weather - When the temperature rises and the amount of water vapor in a piece of air remains constant, the relative humidity decreases.</p><p style=";text-align:left;direction:ltr"> Relative humidity depends on both temperature and the amount of water vapor present in the air. As the temperature increases, the air&#39;s ability to hold water vapor increases, reducing the ratio of existing water vapor to the amount the air can hold at the new temperature, and thus the relative humidity decreases.</p>
