Why is water a liquid at normal earth conditions when it should be a gas based upon its size?

Water is a liquid at normal Earth conditions primarily due to its strong hydrogen bonding, which arises from the polarity of its molecules. These bonds create a cohesive force that holds the molecules together, allowing water to remain in a liquid state at room temperature. Additionally, water has a relatively high boiling point compared to other small molecules, further contributing to its liquid state under typical atmospheric conditions.
