Question

A sealed glass bottle containing air at at-
mospheric pressure (101 kPa) and having a
volume of 43 cm3 is at 34C. It is then tossed
into an open fire.
When the temperature of the air in the bot-
tle reaches 169C, what is the pressure inside
the bottle? Assume any volume changes of
the bottle are negligible.
Answer in units of kPa

Answer 1

pV=nRT so p=nRT/V and the ratio of the pressures will be the ratio of the absolute temperatures, as the volume and the amount of gas remain the same.

p=(101kPa)(169+273)/(34+273)= (101kPa)(1.44)=145 kPa.

Answer 2

Thank you :)

Answer 3

You are quite welcome.
