What will happen if we keep the metallic can in a water bath having cold water. Give reason

when a cold metallic is put in a water bath with cold water than the laws of thermodynamics and calorimetry suggests that both the solid and the liquid will engage in heat exchange until they attain equilibrium.

once they both are at equal temperature, no heat transfer will continue and the bodies will just stat in a packed atmosphere.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
