Answer:
180psi
Step-by-step explanation:
Step one:
given data
P1= 900 psi
T1= 350°C
P2=?
T2=70°C
Required
The final pressure P2
<em>Gay-Lussac's Law: The Pressure Temperature Law. This law states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. With an increase in temperature, the pressure will go up</em>
Applying the expression
P1/T1= P2/T2
substitute:
900/350= P2/70
2.57=P2/70
cross multiply
P2= 2.57*70
P2=180psi
Answer: B -4
Step-by-step explanation: I think it is B because -4 is smaller than A,C and D.
Answer:
y=x7 X 5
Step-by-step explanation:
Completely different...
.15*.15*.15*500
500(.15^3)=1.6875
500(.45)=225
The awnser is D but could also maybe be B
