A) \[\frac{3\alpha }{PK}\]
B) \[3PK\alpha \]
C) \[\frac{P}{3\alpha K}\]
D) \[\frac{P}{\alpha K}\]
Correct Answer: C
Solution :
[c] Due to thermal expansion \[\frac{\Delta V}{V}=3\alpha \Delta T\] ...(1) Volumetric strain due to external pressure \[\frac{\Delta V}{V}=\frac{P}{K}\] ...(2) Equating both equations we get \[3\alpha \Delta T=\frac{P}{K}\Rightarrow \Delta T=\frac{P}{3\alpha K}\]You need to login to perform this action.
