Homework Statement
A gas bubble with a volume of 0.10 cm^3 is formed at the bottom of a 10.0 cm deep container of mercury. If the temperature is 27C at the bottom of the container and 37C at the top of the container, what is the volume of the bubble just beneath the surface of the mercury? assume that the surface is at atmospheric pressure.
Homework Equations
P1V1/T1=P2V2/T2
P=Po+pgh
The Attempt at a Solution
P2=Po+pgh
P2= 1.01x10^5Pa + (13.6x10^3kg/m3)(9.81m/s)(1.0x10^-3m)
P2= 101130Pa
P1V1/T1=P2V2/T2 > V2=P1V1T2/T1P2
V2=(1.01x10^5Pa)(1.0X10^-3 m^3)(300K)/(310K)(101130Pa)
V2=9.66x10^-4 m^3
The answer in the back differs with mine and I have tried to redo the problem many times.
