Question

An insulated cylinder of volume 60 cm^3 is filled with a gas at 27^ C and 2 atmospheric pressure. Then the gas is compressed making the final volume as 20 cm^3 while allowing the temperature to rise to 77^ C. The final pressure is \_ \_ \_ \_ atmospheric pressure.

Accepted Answer

Correct answer: 7. (7) PV= nRT P_1V_1RT_1= P_2V_2RT_2 2 10^5 60300= P_2 20350 P_2= 2 10^5 7 36 P_2=7 10^5=7 atm

$An insulated cylinder of volume 60 cm^{3} is filled with a gas at 27^{\circ} C and 2 atmospheric pressure. Then the gas is compressed making the final volume as 20 cm^{3} while allowing the temperature to rise to 77^{\circ} C . The final pressure is____atmospheric pressure.$
