A) 736.18 mm
B) 820.20 mm
C) 784.15 mm
D) 857.14 mm
Correct Answer: D
Solution :
Given that: \[{{V}_{1}}=100ml,{{P}_{1}}=720mm,{{V}_{2}}=84ml,{{P}_{2}}=?\] By using \[{{P}_{1}}{{V}_{1}}={{P}_{2}}{{V}_{2}}\] [According to the Boyle's law] \[{{P}_{2}}=\frac{{{P}_{1}}{{V}_{1}}}{{{V}_{2}}}=\frac{720\times 100}{84}=857.142\] Hence, \[{{P}_{2}}=857.14mm\]
