The term which can differentiate thermodynamics from other sciences is ____.

a. Pressure
b. Temperature
c. Mass
d. None of the above

Correct Answer : b. Temperature

Explanation :

Temperature plays a very important role in thermodynamics as force does in static and velocity does in dynamics. Temperature is the term through which we can differentiate between hot and cold. When two bodies are brought in physical contact with each other and one body has more temperature than other then hear transfer takes place from hot body to cold one. After some time they attain a common temperature and then they are in a thermal equilibrium. These phenomena are very important in thermodynamics.
