The specific heat of water is.
Correct answer: B. 4.2 j/g.K
- A. 4.2 kJ/mol/K
- B. 4.2 j/g.K
- C. 4.61/g/K
- D. 42/g/K
Explanation
The specific heat capacity of water is approximately 4.2 joules per gram per degree Celsius (J/g/°C). This means that it takes 4.2 joules of energy to raise the temperature of 1 gram of water by 1 degree Celsius.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
