Question

PLEASE HELP ME

Tyler found his iguana playing with a soccer ball in the basement that contained 400kPa of pressure, held 3L and was at 300K. Devin took the ball in the garage where the pressure in the ball became 350kPa and the temperature was 250K. How much space did the ball take up? Question 14 options:
1. 2.9 L
2. 2.0 L
3. 2.8 L
4. 2.5 L
5. 2.7 L

Answer 1

Hello!

The ball took up 2,9L

To solve this problem, we should apply the ideal gas law and clear for n (the number of moles), as this value doesn't change when Devin takes the ball to the garage:


`n= (P1*V1)/(RT1)=(P2*V2)/(RT2)`

Now, we should clear this equation to find V2, as this is the value we are looking for:


`V2= (P1*V1*T2)/(P2*T1)= (400kPa*3L*250K)/(350kPa*300K)=2,857L`≈2,9L

Have a nice day!
