Physics · Thermal equilibrium and the concept of temperature, zeroth law of thermodynamics
Use of thermometer is based on which law of thermodynamics?
Use of thermometer is based on which law of thermodynamics?
- A. zeroth
- B. First
- C. second
- D. Third
Step-by-step solution
A thermometer measures temperature by relying on thermal equilibrium between the thermometer and the object. The zeroth law of thermodynamics defines temperature and establishes that if two systems are in thermal equilibrium with a third, they are in equilibrium with each other, which is the basis for temperature measurement.
