Why is H2O liquid at room temperature?

Why is H2O liquid at room temperature?

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.

What is the reason of being liquid state of H2O while h2s is gas?

Water is a liquid while hydrogen sulphide is a gas because the hydrogen bonding in water causes the water molecules to be associated with each other due to intermolecular forces of attraction.

Why is nitrogen a gas at room temperature?

Nitrogen has just one type of atom, so it is an element. It’s found naturally as a molecule, each containing two nitrogen atoms. This gives it a chemical formula of N₂. Nitrogen has a low melting and boiling point and is a gas at room temperature.

Why h2o is liquid and nh3 is gas?

given that the nitrogen ATOM has ONLY the one lone pair..the opportunity for intermolecular interaction via hydrogen-bonding is diminished with respect to water. i.e. nitrogen IS LESS electronegative than oxygen, and polarity is not pronounced in the ammonia molecule as compared to the water molecule…

Why is air a gas at room temperature?

Air, helium and chlorine are gases at room temperature….Gases.

Property Reason
They flow and completely fill their container The particles can move quickly in all directions

Why is water a liquid at room temperature when all other chemically similar substances are gases at room temperature?

What is the chemical formula of water? Why is water a liquid at room temperature when all other chemically similar substances are gases at room temperature? Hydrogen bonding keeps the water molecules close together. Since the hydrogen atoms get less than their fair share of electrons, they end up slightly positive.

Why is water a liquid at room temperature when all other chemically similar substances are gases at room temperature *?

It is liquid because of hydrogen bonding. When water is a liquid its molecules are closer than when it is a solid. Both the oxygen atoms, and the hydrogen atoms are fighting over the electrons they are supposed to be sharing.

Why h20 is liquid and h2s is gas Class 11?

Oxygen has smaller size and higher electronegativity as compared to sulphur. Therefore, there is extensive hydrogen bonding in H2O, which is absent in H2S. Molecules of H2S are held together only by weak van der Waal’s forces of attraction. Hence, H2O exists as a liquid while H2S as a gas.

Why at room temperature fluorine and chlorine are gases bromine is a liquid and iodine is a solid?

In fluorine, the electrons are tightly held to the nuclei. The electrons have little chance to wander to one side of the molecule, so the London dispersion forces are relatively weak. It is only at temperatures between -7 °C and 59 °C that fluorine and chlorine are gases, bromine is a solid, and iodine is a solid.

Why is nitrogen a gas at room temperature and carbon is a solid?

Why is nitrogen a gas at room temperature and carbon is a solid? Less energy is required (lower temperatures) to overcome these interactions. It is the LDFs (not the bonds within the molecules) that are overcome when the solid melts.
