Q. Write a note on lead - acid storage battery. Answer:  A storage cell that can operate both as a voltaic cell and as an electric cell, When operating as a voltaic cell it supplies electrical energy and as a result eventually becomes "run down". It must then be reacharged, When being recharged, the cell operates as an electrolytic cell. Thus, storge cell has the great advantaged of its ability to work both ways, to receive electrical energy and also to supply it: Construction : The common example of a storage cell is the lead storage cell. One of its electrodes is made of lead. The other electrode is made of lead dioxide (PbO_{2}) or rather a paste of PbO_{2} is pressed into a grid made of lead.

 Application of Expansion 1. Expansion property is used in mercury thermometers and liquid thermometers.  2. Suitable gap between rails of railway track is kept to provide scope for expansion. 3. Long compound walls are also build by keeping certain gap. 4. Isothermal and adiabatic expansions and compressions of gas are used in studying heat cycles and it is used to study heat engines. 5. In manufacturing of heat exchangers, designer has to take into account the expansion of components used in it.  6. Depending upon values of linear expansion, aerial expansion or cubical expansion, thermal properties of material can be studied.
