A) 13.65 cm
B) 27.3 cm
C) 38.6 cm
D) 64.6 cm
Correct Answer: D
Solution :
[d] Using Charle's law, we have \[\frac{V}{T}=\] constant \[\Rightarrow \frac{\frac{l}{2}+5}{373}=\frac{\frac{l}{2}-5}{273}\] As the piston moves 5 cm, the length of one side will be \[\left( \frac{l}{2}+5 \right)\] and other side\[\left( \frac{l}{2}-5 \right)\]. On solving this equation, we get \[l=64.6\text{ }cm.\]You need to login to perform this action.
