What is the final volume?

Question

An air bubble has a volume of 0.600 L at 28 ∘C. What is the final volume, in liters, of the gas when the temperature changes to each of the following, ifP and n do not change?

1. 0 ∘C
2. 430 K
3. -20 ∘C
4. 590 K

Answer 1

When P is constant, you are dealing with Charles Law, just as in your previous question. Here you will solve for V2 from the equation V1/T1 = V2/T2. For problem #1, you have...

V1 = 0.600 L

T1 = 28ºC + 273 = 301K (always use K for temp)

V2 = ?

T2 = 0ºC + 273 = 273K

0.600 L/301K = V2/273

V2 = (0.600 L)(273K)/301K = 0.544 L
