How would the volume of an #18*g# mass of water change if its temperature changed by over #100# #""^@C#?

Answer:

Well, there is a PHASE CHANGE associated with your question......

Explanation:

#18*g# clearly constitutes a mole of water. However, the water can be condensed or in the gaseous phase. Water is quite involatile, and #18*g# of ice or water indeed contains a molar quantity of #OH_2# molecules, i.e. #2xxN_A# #H# atoms, and #N_A# #O# atoms; #18*g# in total.

At normal pressures, if we heat the water up over #100# #""^@C#, a phase change occurs, and the water enters the gaseous phase. And #18*g# of GASEOUS water would indeed occupy #22.4*L#....of course the temperature of the gas phase would also change the volume.
