A) \[{{10}^{-4}}\]
B) \[{{10}^{-2}}\]
C) \[{{10}^{-3}}\]
D) \[{{10}^{2}}\]
Correct Answer: A
Solution :
The coefficient of volume expansion is given by \[\gamma =\frac{\Delta \rho }{{{\rho }_{1}}\times \Delta T}\] where, \[{{\rho }_{1}}\]is density, T is temperature. \[\gamma =\frac{{{\rho }_{1}}-{{\rho }_{2}}}{{{\rho }_{1}}({{T}_{2}}-{{T}_{1}})}\] \[=\frac{10-9.7}{10\,(100-0)}=3\times {{10}^{-4}}\] Coefficient of linear expansion is \[\alpha =\frac{\gamma }{3}=\frac{3\times {{10}^{-4}}}{3}={{10}^{-4}}\]You need to login to perform this action.
