One kcal is equal to _.
Correct answer: B. 4180 J
- A. 4.18 J
- B. 4180 J
- C. 2.09 J
- D. 2090 J
Explanation
One Kcal = 4.18 KJ or 4180 JOne kilocalorie (kcal) is equal to 4,184 joules. The kilocalorie is a unit of energy commonly used in the context of nutrition to quantify the energy content of food. In the International System of Units (SI), the joule is the standard unit of energy, and 1 kcal is equivalent to 4,184 joules

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.
