Question

A liquid has a volume $V_1$ at temperature ${\theta }_1$. The temperature is increased to ${\theta }_2$. If $\gamma$ is the coefficient of cubic expansion, the increase in volume is given by

• A. $V_1\gamma ({\theta }_2-{\theta }_1)$
• B. $V_1\gamma {\theta }_2$
• C. $V_1+V_1\gamma {\theta }_2$
• D. $V_1[1+\gamma ({\theta }_2-{\theta }_1]$

Answer 1

The correct option is A $V_1\gamma ({\theta }_2-{\theta }_1)$

$V_2-V_1=\gamma V_1\times$.{change in temperature)
