Sagot :
Answer:
67.824
Explanation: You want to use the combined gas law equation (P1*V1)/(n1*T1)=(P2*V2)/(n2*T2). So first cross out what remains constant, so volume(V) and I assume moles (since it was not mentioned as a change). Then you can solve algebraically for the answer!
Hope this helped!
The new pressure will be 139.2 kpa .
What is the combined Gas Law?
According to combined gas law,
[tex]\rm\dfrac{PV}{nT} = R[/tex]
In the Combined Gas Law,if we change either one of the variables the others will also change.
When the moles of the gas is constant , the above equation can be written as ,
[tex]\rm \dfrac{P'V'}{T'}= \dfrac{PV}{T}[/tex]
Given is P = 84kpa , T= 350⁰ C and T' = 350+230=580⁰ C , V=V' , P'=?
So we will substitute the values in the above formula keeping volume constant.
[tex]\rm \dfrac{P'}{T'}= \dfrac{P}{T}[/tex]
[tex]\rm\dfrac{P'}{580}= \dfrac{84}{350}[/tex]
[tex]\rm P' = \dfrac{84\times 580}{350}[/tex]
[tex]\rm P'= 139.2 \;kpa[/tex]
Therefore the new pressure will be 139.2 kpa .
