Question

the apparent volume expansion coefficient of a liquid in steel vessel is A and that in aluminium vessel is B . if the thermal coefficient of linear expansion is C , then that of steel will be:
A-B+3C/3
B-A+3C/3
A-B-3C/3
B-A-3C/3​

Answer 1

Answer:

$\frac{B-A+3C}{3}$

Explanation:

We are given that

Apparent volume expansion coefficient of a liquid in steel vessel=A

Apparent volume expansion coefficient of a liquid in aluminium vessel=B

Thermal coefficient of linear expansion of aluminium vessel=C

We have to find the thermal coefficient of linear  expansion of steel.

$r_{rea}=r_{app}+r_{container}$

$r_{rea}=r_{\frac{app}{steel}}+r_{steel}=r_{\frac{app}{Al}+r_{Al}$

$B+3C=A+3D$

$3D=B-A+3C$

$D=\frac{B-A+3C}{3}$

Answer:$\frac{B-A+3C}{3}$
