Based on gas laws:
PV/T = Constant, P = Pressure, V = volume, T = Temperature (K)
Therefore,
P1V1/T1 = P2V2/T2
P1 = 10 psig
V1 = 10 in^3
T1 = 65°F = 291.483 K
P2 = ?
V2 = 1.5 in^3
T2 = 180°F = 355.372 K
Rearranging the equation,
P2 = P1V1T2/T1V2 = (10*10*355.372)/(291.483*1.5) = 81.279 psig
I believe that it is B. Hope this helps!
Answer:
see below
Step-by-step explanation:
16+20/t
Let t=4
16 + 20/4
First we divide
16 + 5
Then we add
21
Make sure the number is rational if it isn’t
