Question

Question 16 5 pts An ideal gas is at a pressure of 1.8 atm and has a volume of 4 L. If the gas is compressed to a volume of 1 L while its temperature is held constant, what is the resulting pressure to the nearest tenth of an atm? D Question 17 5 pts A balloon filled with an ideal gas initially has a temperature of 16 C and a volume of 4.0 L If the heated to 112 C while the pressure in the balloon is held constant, what volume will the balloon expand to? Round to the nearest tenth of a liter. Hint: remember to use the appropriate temperature scale! gas in the ballon is Question 18

Explanation / Answer

according to the ideal gas equation PV=nRT

here the R & T held constant hence P1V1=P2V2

P2=P1V1/V2=1.8*4/1=7.2atm

|In the second problem Pressure maintained as constant

then V proportional to T

V1/T1=V2/T2

v2=(V1/T1)*T2=(4/289.15)*385.15=5.3lit
