Why is water liquid at room temperature

Explanation:

At room temperature (anywhere from zero degree centigrade to 100 degrees centigrade), water is found in a liquid state. This is because of 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.

when at room temperature, water remains a liquid because the molecules aren't moving super fast or super slow

Explanation: for water to become a solid it must be frozen, then the molecules are barely moving and are vibrating in place. for water to be a gas the water has to be 100 degrees farenheight, which is like boiling, and then it turns to a steam which is a gas. so water is liquid at room temperature because the molecules aren't moving super fast or super slow. hope this helps

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
