Answer:
8,19 L
Explanation:
The combined gas law is a equation that can be used <em>when the initial and final conditions -</em>pressure,volume,amount of moles,temperature-, <em>of a gas change</em> during a process. It can be written:
If the amount of the gas remains constant, then n1=n2 and we have:
For the problem we have:
<em>Note: When working with gases is important to use </em><em><u>absolute temperature values (°K, °K=°C+273,15):</u></em>
P1=1 atm, V1=2,5L, T1=25+273,15=298,15°K
P2=0,3 atm, V2=?, T2=20+273,15=293,15°K
The new volume of the balloon is 8,19 L.
