A gas sample occupying 4.3 L at 1.2 atmospheres of pressure and 37°C is heated to 74°C and allowed to expand to 4.4 L. Using the ideal gas law relating pressure, volume, temperature, and amount of gas, the final pressure of the gas sample is calculated to be 1.3 atmospheres.

1. A sample of gas occupying 4.3 L at 37 °C and 1.2 atmospheres pressure is heated to 74 C and
allowed to expand to 4.4 L What is the final pressure? O a 10 atnm o b 1.3 atm 0c.2-3 atm

Solution
initial final
P1 = 1.2atm P2 =
V1 = 4.3L V2 = 4.4L
T1 = 37+273 = 310K T2 = 74+273 = 347K
P1V1/T1 = P2V2/T2
P2 = P1V1T2/T1V2
= 1.2*4.3*347/310*4.4 = 1.3
b. 1.3atm >>>>answer
