Potential energy stored in a spring => kinetic energy of a toy
Answer:
Option (C) 3
Explanation:
The pH scale is a scale that ranges from 0 to 14. The pH reading has various notifications. These notifications are as follow:
1. If the pH reads between 0 and 6, then the solution is acidic.
2. If the pH reads 7, then the solution is neutral.
3. If the pH reads between 8 and 14, then the solution is basic.
With the above information, option C is the correct answer to the question.
Pv=nRT
where,p=199, R(constant)=8.314, V=4.67 T=30C=293K
n=pv/RT=0.38 moles
