Air in a closed cylinder is heated from 15°C to 36°C. If the initial pressure is 1000 torr, determine what is the final pressure
Bingel [31]

Answer:

1072 torr

Explanation:

To answer this problem we can use <em>Gay-Lussac's law</em>, which states:

  • P₁T₂=P₂T₁

Now we convert the given temperatures into K:

  • T₁ = 15°C ⇒ 15+273.16 = 288.16 K
  • T₂ = 36°C ⇒ 36+273.16 = 309.16 K

We <u>input the data</u>:

  • 1000 torr * 309.16 K = P₂ * 288.16 K

And <u>solve for P₂</u>:

  • P₂ = 1072 torr
