WebbChange in internal energy. dU = (U 2 – U 1) = nC v dT. Internal energy is a function of state only and its change does not depend on path. 2. First law of thermodynamics. The heat … Webb16 apr. 2024 · 0th law of thermodynamics helps us in finding the temperature of a human body. For example, when a thermometer is kept in contact with a human body suffering from fever, the mercury gains heat and it expansion in the thermometer tube. After few seconds, mercury achieves thermal equilibrium with the human body.
