Question

minjo patta hai ma ta innya he pucchaya ​

Answer 1

Answer:

The four fundamental laws of thermodynamics express empirical facts and define physical quantities, such as temperature, heat, thermodynamic work, and entropy, that characterize thermodynamic processes and thermodynamic systems in thermodynamic equilibrium. They describe the relationships between these quantities, and form a basis for precluding the possibility of certain phenomena, such as perpetual motion. In addition to their use in thermodynamics, the laws have interdisciplinary applications in physics and chemistry.

Answer 2

Answer:

physical properties are those properties which can be measured or observed without changing the identity or composition of the substance
