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

c is the answer because when something is left after something evaporates that shows the chemical change.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
