The correct Answer is:
a,b
Invar is an alloy containing `63.8% Fe.36% Ni,0.2 %` carbon that has a very low coefficient of expansion . It is used for balance wheels of watches and in other accurate instrumets , which would atherwise be affected by temperature changes
steel is iron contaioning from `0.1% 2 1.5% C` in the form of comentite (iron carbic `Fe_(2)C)` . The properties pf different steels very ocording tio the percerntage of C and aof metals then , iron present and also acoording to the method of prteparation .
Bell metal is an alloy of copper `60% - 85%`and tin. Bragen is class of alloys of `Cu` and `Sn` . acopper alloy containing no tin , e.g. aluminium bronze is an allow of `Cu ans Al` .since steel is more common invar , we may go for option `(2)` .
