Question

At what temperature, the sample of neon gas would be heated to double its pressure initial volume of gas is reduced by 15% at ${75}^{0}C$?

• A. ${592}^{0}C$
  
• B. ${319}^{0}C$
  
• C. ${789}^{0}C$
  
• D. None
  

Answer 1

Answer: (B)

${319}^{0}C$

$T_1=273+75K=348$

$\frac{P_1{V}_1}{T_1}=\frac{P_2{V}_2}{T_2}$

$\frac{P_1{V}_1}{348}=\frac{2P_1\times 85V_1}{T_2\times 100}=591.6K$

Temperature in $C^0=591.6-273=319C^0$
