it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

it is stable as it is in group 0 which have full outer shells of electrons

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
