Question

if the temperature of water increases from 1 Degree Celsius to 3 degree Celsius then the density of water will?​

Answer 1

Explanation:

Water is an unusual case in that as you cool the substance from 4°C to 0°C, water at a molecular level begins to lose its amorphous properties increasingly become more symmetrical increasing it stability, which intrinsically causes ΔG to increase. As water is cooled, releasing its thermal energy to the environment, causing its Enthalpy of formation to decrease ΔH, the hydrogen bonding or inter-molecular forces between these molecules becomes an increasingly significant variable in determining its stability as the internal energy in Lattice structures is affected by vibrational modes of energy (no particle collisions and no rotation) . The molecules form more distant and farther apart in order to optimize its bonding angle of 109.5° ( a result of it’s Trigonal Pyramidal Geometry) with its hydrogen bonding/inter-molecular forces, ( minimizing electrostatic repulsion due to ring strain) so to preserve this symmetry and maintain stability. This expansion combined with the low temperatures, allow mass contribution via interstitial fluids to distribute much more effectively.

This particular conformation is the most energetically stable conforming to the optimal bonding angle of 109.5° containing the most of amount of space for other interstitial molecules to occupy. It should be noted that other conformations can exist past 4°C, however due to the higher temperature and increased contribution of rotational and translational modes of energy, these conformations are irregular in form, and often not the most energetically favorable.

Answer 2

Decrease as the intermolecular spaces between water molecules will increase
