The volume of a liquid at 10^(@)C is 50 c.c. Find its volume at 100^(@)C? (gamma_(R) of liquid is 7xx10^(-4)//""^(@)C). |

Answer» SOLUTION :Initial volume of the liquid `(V _(1)) = 50 ` c.c Initial temperature `(t _(1) ^(@)C) = 10 ^(@)C:`Final temperature `(t _(2) ^(@) C) = 100^(@) C` Coefficient of real expansion of the liquid `(gamma _(R )) = 7 xx 10 ^(-4) //^(@)C ` from `v _(2) = v _(1) [1 + gamma _(R) (t _(2) - t _(1)) ]` `= 50 [ 1+ 7 xx 100 ^(-4) xx 90] = 53.1 5 cm ^(3)` `therefore v _(2) = 53.15 cm ^(3)` Volume of liquid at `100^(@)C=53.15 cm ^(3)` |
