PLEASE HELP!!!

If a 435 mL sample of gas at 219 °C is allowed to expand (at constant pressure) to a volume of 842 mL, what will be the new temperature (in °C)?

Answer:

424 °C

Step-by-step explanation:

If all other variables are held constant, the missing temperature can be found using the Charles' Law equation:

V₁ / T₁ = V₂ / T₂

In this equation, "V₁" and "T₁" represent the initial volume and temperature. "V₂" and "T₂" represent the final volume and temperature. You can plug the given values into the equation and simplify to find the final temperature.

V₁ = 435 mL V₂ = 842 mL

T₁ = 219 °C T₂ = ? °C

V₁ / T₁ = V₂ / T₂ <----- Charles' Law

435 mL / 219 °C = 842 mL / T₂ <----- Insert values

1.9863 = 842 mL / T₂ <----- Simplify left side

(1.9863) x T₂ = 842 mL <----- Multiply both sides by T₂

T₂ = 424 °C <----- Divide both sides by 1.9863
