MCQ
The compressibility of water is $4 \times 10^{-5}$ per unit atmospheric pressure. The decrease in volume of 100 cubic centimeter of water under a pressure of 100 atmosphere will be
- ✓$0.4 c c$
- B$4 \times 10^{-5} c c$
- C$0.025 c c$
- D$0.004 c c$
✓
Answer
Correct option: A.
$0.4 c c$
$ C=\frac{1}{K}=\frac{\Delta V / V}{\Delta P} \Rightarrow \Delta V=C \times \Delta P \times V$
$ =4 \times 10^{-5} \times 100 \times 100=0.4 c c$
$ =4 \times 10^{-5} \times 100 \times 100=0.4 c c$
