Question

Let ${\gamma }_r$ = Coefficient of real expansion

${\gamma }_a$ = Coefficient of apparent expansion

${\gamma }_a$ = Coefficient of volume expansion of vessel

Then ,${\gamma }_r$ =___.

• A. $({\gamma }_r$+${\gamma }_v$)
• B. $({\gamma }_r$ - ${\gamma }_v$)
• C. $({\gamma }_r\times$${\gamma }_v$)
• D. None of the above

Answer 1

The correct option is A

$({\gamma }_r$+${\gamma }_v$)

The coefficient of real expansion = the sum of coeffiient of apparent expansion and the coefficient of expansion of vessel (all being volume expansion).

In other words, Real expansion = Apparent expansion + expansion of the container
