Current Question (ID: 10734)

Question:
$\text{The pressure applied from all directions on a cube is } P. \text{ The volume elasticity of the cube is } \beta \text{ and the coefficient of volume expansion is } \alpha. \text{ How much should its temperature be raised to maintain the original volume?}$
Options:
  • 1. $\frac{P}{\alpha\beta}$
  • 2. $\frac{P\alpha}{\beta}$
  • 3. $\frac{P\beta}{\alpha}$
  • 4. $\frac{\alpha\beta}{P}$
Solution:
\text{If the coefficient of volume expansion is } \alpha \text{ and the rise in temperature is } \Delta\theta\text{, then: } \Delta V = V\alpha\Delta\theta \Rightarrow \frac{\Delta V}{V} = \alpha\Delta\theta \text{Volume elasticity, } \beta = \frac{P}{\Delta V/V} = \frac{P}{\alpha\Delta\theta} \Rightarrow \Delta\theta = \frac{P}{\alpha\beta}
