Question 1 (2 points)
bogdanovich [222]

Answer:

3.75 L

Explanation:

We can solve this problem by using <em>Charles' law</em>, which states:

  • V₁T₂=V₂T₁

Where subscript 1 stands for initial volume and temperature and subscript 2 for final volume and temperature, meaning that in this case:

  • V₁ = 2.5 L
  • T₂ = 300 K
  • V₂ = ?
  • T₁ = 200 K

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

  • 2.5 L * 300 K = V₂ * 200 K

And <u>solve for V₂</u>:

  • V₂ =  3.75 L
