What is the value of one calorie in a joule?
Correct answer: C. 4.l8J
- A. 4.98J
- B. 7.98J
- C. 4.l8J
- D. 8.21J
Explanation
One kilocalorie is equal to 4.184 joules so one calorie would be equal to "4.18" joules hence the answer C.

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.
