Question

4.A balloon containing an ideal gas sits in a constant pressure chamber. The temperature of the chamber is raised from 275 K to 315 K. If the balloon started at a volume of 0.03 m3, what is the new volume after the temperature change?

Answer 1

To solve this problem, we must take into account the equation:

`PV=nRT`

So, for an isobaric transformation (constant pressure), an increase in volume generates an increase in temperature. This can be written as:

`(V_1)/(T_1)=(V_2)/(T_2)`
`(0.03)/(275)=(V_2)/(375)\Rightarrow V_2=(0.03*375)/(275)=0.04091m^3`

Thus, the new volume will be 0.04091m^3
