Question

Why is water liquid at room temperature​

Answer 1

because of the temperature of the environment

Answer 2

Answer:

the tiny, weak hydrogen bonds which, in their billions, hold water molecules together for small fractions of a second.

Water molecules are constantly on the move. If they are moving fast enough they become a gas. A gas is a physical state of matter where the molecules are far apart and moving very quickly. But, because of the hydrogen bonds, as water molecules come together they stick to one another for a small, but significant amount of time. This slows them down, and holds them closer to one another. They become a liquid; a different state of matter where the molecules are closer and slower than in a gas.
