A metal gas cylinder is heated from 181 K to 296 K. If the original pressure was 256 psi, what is the pressure after heating also in psi?

Answer:

419 psi

Explanation:

Assuming the gas behaves ideally, we can solve this problem by using Gay-Lussac's law, which states:

  • P₁T₂=P₂T₁

Where subscript 1 stands for the initial conditions and 2 for the final ones, meaning that in this case:

  • P₁ = 256 psi
  • T₂ = 296 K
  • P₂ = ?
  • T₁ = 181 K

We input the data:

  • 256 psi * 296 K = P₂ * 181 K

And solve for P₂:

  • P₂ = 419 psi
