Humidity refers to the amount of moisture or water vapor present in the air. It plays a significant role in our daily weather and can affect how we feel. For example, on a hot day, high humidity can make the temperature feel even warmer, while low humidity can make it feel cooler. There are two main types of humidity: relative humidity and absolute humidity. Relative humidity measures how much moisture is in the air compared to the maximum amount it can hold at a specific temperature. Absolute humidity, on the other hand, measures the actual amount of water vapor in a given volume of air, regardless of temperature.
