A) 400 c.c.
B) 510 c.c.
C) 310 c.c.
D) 350 c.c.
Correct Answer: C
Solution :
Given initial volume \[\left( {{V}_{1}} \right)=300cc\], initial temperature \[\left( {{T}_{1}} \right)={{27}^{o}}C=300K\], initial pressure \[\left( {{P}_{1}} \right)=620mm\], final temperature \[{{T}_{2}}={{47}^{o}}C=320K\]and final pressure \[\left( {{P}_{2}} \right)=640mm\].We know from the general gas equation \[\frac{{{P}_{1}}{{V}_{1}}}{{{T}_{1}}}=\frac{{{P}_{2}}{{V}_{2}}}{{{T}_{2}}}\]\[=\frac{620\times 300}{300}=\frac{640\times {{V}_{2}}}{320}\] Þ\[{{V}_{2}}=310cc\]
