Answer:

260 kPa

Step-by-step explanation:

To answer this problem we can use Gay-Lussac's law, which states that at a constant volume (such as is the case with a rigid container):

  • P₁T₂=P₂T₁

Where in this case:

  • P₁ = 340 kPa
  • T₂ = 273 °C ⇒ 273 + 273.16 = 546 K
  • P₂ = ?
  • T₁ = 713 K

We input the data:

  • 340 kPa * 546 K = P₂ * 713 K

And solve for P₂:

  • P₂ = 260 kPa
