Ask Your Teacher
In a common demonstration, a bottle is heated and stoppered with a hard-boiled egg that's a little bigger than the bottle's neck.
When the bottle is cooled, the pressure difference between inside and outside forces the egg into the bottle. Suppose the bottle
has a
volume of 1.25 L and the temperature inside it is raised to 79.0°C while the pressure remains constant at 1.00 atm because
the bottle is open
(a) How many moles of air are inside? (Enter your answer to at least three significant figures. Use 8.31 J/mol K for the gas
constant and assume 1 atm =
101,300 Pa.)
moles
Now the egg is put in place, sealing the bottle. What is the gauge pressure (in kPa) inside after the air cools back to the
(b)
ambient temperature of 20.0°C but before the egg is forced into the bottle?
kPa
