The foundation for quantifying the thermodynamic property of temperature is provided by___________________?
Show answer Hide answer
Answer: A. zeroth law of thermodynamics
Explanation
The zeroth law establishes that if two bodies are in thermal equilibrium with a third, they are in equilibrium. This fundamental concept enables the consistent calibration and use of thermometers to quantify thermal states. Without the logical framework provided by this law, defining temperature as a measurable property would be impossible. R. H. Fowler formulated the zeroth law long after the first and second laws were already established. Thermal equilibrium means no net heat flows between objects when they are placed in direct contact. The law justifies the transit property of temperature measurement across different observational reference frames.
The first law of thermodynamics deals exclusively with energy conservation and work-heat correlations. The second law establishes entropy directionality and thermal engine efficiency limits rather than temperature definition. The third law addresses the behavior of systems as their absolute temperature approaches zero Kelvin.

Show answer Hide answer
Answer: B. point functions
Thermodynamic coordinates describe the precise physical state of a system at any given moment. Properties such as pressure, temperature, and density depend entirely on current conditions rather than history. Quantities t...
Q4. Sudden fluid expansion into a vacuum through a large orifice is termed___________________?
Show answer Hide answer
Answer: A. free expansion
Free expansion occurs when a fluid rushes into an evacuated chamber. No external mechanical work is performed because the boundary does not move. The process is highly irreversible due to unresisted fluid expansion. Joul...
Q5. Leaving the door of an operational refrigerator open inside a closed room results in____________________?
Show answer Hide answer
Answer: C. The room will be gradually warmed up.
A refrigerator removes interior heat and exhausts it into the surrounding room air. The electrical energy consumed by the compressor is also converted into thermal heat. Consequently, leaving the refrigerator door open a...
