The specific heat of water is :
Correct answer: C. 4180 J/kg.K
- A. 1/Kg
- B. 4.18 J/Kg.K
- C. 4180 J/kg.K
- D. 2090 J/kg.K
Explanation
Option C is correct since 4180 J/Kg K is the correct value of the specific heat capacity of water.Option A is incorrect since the value has the units of heat capacity.Option B is incorrect since it should have stated 4.18kJ instead of 4.18J.Option D is incorrect since 2090 J/Kg K is the specific heat capacity of ice.

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
