WHY IS SIGN CONVENTIONS OF THERMODYNAMICS IN CHEMISTRY IS DIFFERENT FROM SIGN COVENTIONS OF PHYSICSS THERMODYNAMICS
According to the Avogadro's law, equal volumes of gases at the same temperature and pressure should contain:
Equal number of molecules
Same molartity
Same kinetic energy
Same potential energy
difference between mixture and compound?
when two substance A and B are powdered togetherin a pestle and mortar , a large amount of heat is given out and a substance C is formed . the properties of C are found to be differnt from A and B is the substance be compound or element if any then why?
