Question

need help asap dont understand this
Question 1.What is the final volume of a 4.0 L gas sample that is subjected to a temperature change from 22.0 °C to 30.0 °C and a pressure change from 1.0 atm to 0.5 atm? (Points : 1)
10.8 L
1.95 L
8.24 L
None of the above are correct.
Question 2. What is the volume of gas at 2.00 atm and 200 K if its original volume was 300 L at 0.250 atm and 400 K? (Points : 1)
422.3 L
18.75 L
245.1 L
The volume doesn't change.

Answer 1

\(\sf \huge Use: ~\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}\)

Answer 2

You need to use temperature in the absolute scale, Kelvin.
