Viscosity is the resistance of liquid to flow.

Temperature, Internal Energy and Pressure are state functions.

1 Kilocalorie is equal to 4184 J.
A calorie is the amount of heat required to raise the temperature of 1 gram of water by 1°C.

Oxidation occurs at anode.
Electron flow from anode to cathode.

SCUBA stands for Self Contained Underwater Breathing Apparatus. It is used for breathing underwater.
Pure mixture of 50% both is dangerous.
Normal ratio of both is not used for deep depth.
Maximum Helium as 96% is used in deep dive to prevent from Nitrogen Narcosis.
Too much Oxygen is dangerous.

Kw is ionic product of water.
Kw tells us about strength of water in making H+ and OH-.
H+ makes water acidic and HO- makes water basic.
Pure water has equal amount of H+ and HO-.

An electrochemical cell that converts chemical energy into electrical energy by a spontaneous redox reaction.
Lead storage battery works on spontaneous redox reactions.
Voltaic cell is also called Galvanic cell.
