A) 13.65 cm
B) 27.3 cm
C) 38.6 cm
D) 64.6 cm
Correct Answer: D
Solution :
Using Boyle?s law, we have \[\frac{V}{T}=\]constant Þ \[\frac{\frac{l}{2}+5}{373}=\frac{\frac{l}{2}-5}{273}\] 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 cm.You need to login to perform this action.
