The specific heat capacity of water is a crucial concept in thermodynamics, indicating how much energy is needed to raise the temperature of a substance. For water, the correct value in SI units is:

Correct Answer

D. 4200 J/kgK

Explanation

This means that it takes 4200 joules of energy to raise the temperature of one kilogram of water by one degree Celsius (or one Kelvin). This high specific heat capacity is why water is effective at regulating temperature in natural environments.

Additional Information

  • Water's high specific heat capacity helps in climate moderation.
  • It plays a vital role in biological processes.
  • Understanding this property is essential in various scientific fields.
