Question

The real coefficient of volume expansion of glycerin is 0.000597 per°C and linear coefficient of expansion of glass is 0.000009 per°C. Then the apparent volume coefficient of expansion of glycerin is

• A. 0.000558 per°C
• B. 0.00057 per°C
• C. 0.00027 per°C
• D. 0.00066 per°C

Answer 1

Answer: (B)

0.00057 per°C

Answer 2

As we know $\gamma_{\text{real}} = \gamma_{\text{app.}} + \gamma_{\text{vessel}}$

⇒ $\gamma_{\text{app.}} = \gamma_{\text{glycerine}} - \gamma_{\text{glass}}$

$= 0.000597 - 0.000027 = 0.00057/{^\circ}C$
