The pressure in an automobile tire is 2.0 atm at 27°C. At the end of a journey on a hot summer day the pressure has risen to 2.2 atm. What is the temperature of the air in the tire? a. 272.72 K b. 330 K c. 0.014 K d. 175 K

Hey there!

For this we can use the combined gas law:

We are only working with pressure and temperature so we can remove volume.

P₁ = 2 atm

T₁ = 27 C

P₂ = 2.2 atm

Plug these values in:

Solve for T₂.

Convert this to kelvin and get 302.85 K, which is closest to B. 330 K.

Hope this helps!

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
