A) 0.4%
B) 0.2%
C) 0.1%
D) 0.8%
Correct Answer: A
Solution :
Initial temperature \[{{T}_{1}}=250K\] Final temperature \[{{T}_{2}}=250+1=251K\] From the Charles law, \[\frac{{{P}_{1}}}{{{P}_{2}}}=\frac{{{T}_{1}}}{{{T}_{2}}}\] \[{{P}_{2}}=\left( \frac{{{T}_{2}}}{{{T}_{1}}} \right){{P}_{1}}\] \[=\frac{251\times 1}{250}=1.004\] Hence, change in pressure, =1.004-1=0.004 =0-4%You need to login to perform this action.
