Question

the pressure inside a 1.0ml balloon at 25 degree celcius was 750 mmhg . What is the pressure inside the balloon when it is cooled to -40 degree celcius

Answer 1

the degree would get decreased since the balloon is getting cooler so the air gets tenser

Answer 2

\[\frac{ P_{1}V_{1} }{ T_{1} }=\frac{ P_{2}V_{2} }{ T_{2} }\]
in order for this proportion to work, you have to convert the temperatures to Kelvin first

after that, let P1, V1, and T1 be your original pressure, volume, and temperature, and P2, V2, and T2 be your final pressure, volume, and temperature. plug in the appropriate quantities and solve for P2.
