The heat capacity per mole of water is (R is universal gas constant)A.

1.	The heat capacity per mole of water is (R is universal gas constant)A. 9RB. `9/2R`C. 6RD. 5R
Answer» Correct Answer - A We treat water like a solic. For each atom average energy is `3k_(B)T.` Water molecule has three atoms, two hydrogen and one oxygen. The total energy of one mole of water is `U=3xx3k_(B)TxxN_(A)=9RT" "(thereforeK_(B)=(R)/(N_(A)))` `therefore` heat capacity per mole of water is `C=(DeltaQ)/(DeltaT)=(DeltaU)/(DeltaT)=9R`
