1.	A metal block is heated through 10^@Ctill the volumeof it changes by 0.31%. Calculate the coefficient of linear expansion of block.
Answer» SOLUTION :`(DELTA V)/(V) = (0.31)/(100)` ` Delta T = 10^@C` As` Delta V = gamma V Delta T` ` (Delta V)/(V) = gamma Delta T` ` rArr gamma = (Delta V)/(V Delta T) = (0.31)/(100 xx 10)- 0.00031` As`alpha = gamma / 3 = (0.00031)/(3) = 0.0001^@C^(-1)`
