Density of substance at

{0^0}C

is 10 g/cc and at

{100^0}C

, its density is 9.7 g/cc. The coefficient of linear expansion of the substance is

View answer and explanation

Correct option: A

1.03\mathrm{ \times }{10^{ - 4}}

Option A (

1.03\mathrm{ \times }{10^{ - 4}}

) is correct because it is derived from the density variation with temperature and the relationship between linear and volume expansion coefficients.
