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
