Question

If 900 joule per gram of heat is exchanged at boiling point of water then what is increase in entropy. Please give answer in joule per mole

Answer 1

If 900 joule per gram of heat is exchanged at boiling point of water then what is increase in entropy. Please give answer in joule per mole...

solution : given, 900J/g of heat is exchanged at boiling point lf water.

we know, molecular mass of water = 18g/mol

so, heat required per mole , H = 900 × 18 J/mol

boiling point of water in Kelvin = 373K

now, entropy = heat/boiling point of water in Kelvin.

= 900 × 18/373

= 43.4 J/mol/K
