When HCl is added to pure water, HCl molecules lose protons, while water molecules gain protons. In this reaction, water is

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements

explanation:

0.07 g/cm³

1.37 g/cm³

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 .
