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
Kruka [31]

Hey there!

For this we can use the combined gas law:

\frac{P_{1}V_{1} }{T_{1}} = \frac{P_{2}V_{2} }{T_{2}}

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

\frac{P_{1} }{T_{1}} = \frac{P_{2} }{T_{2}}

P₁ = 2 atm

T₁ = 27 C

P₂ = 2.2 atm

Plug these values in:

\frac{2atm}{27C} = \frac{2.2atm}{T_{2}}

Solve for T₂.

2atm = \frac{2.2atm}{T_{2}}*27C

2atm * T_{2}={2.2atm}*27C

T_{2}={2.2atm}\div2atm*27C

T_{2}=1.1*27C

T_{2}=29.7C

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

Hope this helps!

Write the balanced chemical equation for the Haber-Bosch process, that is, the combination of nitrogen and hydrogen to form ammo
RoseWind [281]
The balanced chemical equation for the Haber-Bosch process is N₂(g) + 3H₂(g) → 2NH₃(g). The Haber-Bosch process played a significant role in boosting agriculture back in the day. It paved the way for the industrial production of ammonia which is used in the manufacture of fertilizers. The process involves reacting atmospheric N₂ with H₂ using a metal catalyst under high temperature and pressure.
