Question

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? *

Answer 1

Answer:

1072 torr

Explanation:

To answer this problem we can use Gay-Lussac's law, 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 input the data:

• 1000 torr * 309.16 K = P₂ * 288.16 K

And solve for P₂:

• P₂ = 1072 torr
