Here is the graph, hopefully the next person can get it
Answer:
3 °C
Explanation:
The pressure is constant, so this looks like a case where we can use Charles’ Law:
Invert both sides of the equation.
Multiply both sides by <em>V</em>₂
<em>V</em>₁ = 13.3 L; <em>T</em>₁ = (55 + 273.15) K = 328.15 K
<em>V</em>₂ = 11.2 L; <em>T</em>₂ = ?
