Answer: Total work produced = 1.355 × 10^5 KJ
Explanation:
Substance :H2O, V1=1m3
State1= sat. liquid, T1=200°C, x1=0
State2= sat.mixture, T1=200°C, x2= 0.8
v1=vf=0.001157m3/kg, vg=0.12721m3/kg
P1=P2=Psat. =1554.9 KPa
v2= vf+x2 (vg-vf) =0.001157 +0.8(0.12721-0.001157)=0.102m3/kg
V2= V1×v2/v1 = 1× 0.102/0.001157 =88.159m3
W= P(V1-V2) =1554.9(88.152- 1) = 1.355x10^5KJ
Answer:
The heat energy changes into the mechanical energy which moves the car and the chemical energy that stored in the fuel changes by burning into the thermal (the heat) energy in the car engine.
Explanation:
Answer:
Hooke's law describes the elastic properties of materials only in the range in which the force and displacement are proportional. Hooke's law states that the applied force F equals a constant k times the displacement or change in length x, or F = kx. the maximum extent to which a solid may be stretched without permanent alteration of size or shape, is called elastic limit

Answer:
See explanation
Explanation:
Acids and bases contain ions that interact with water. According to the Arrhenius definition, acids are substances that produce hydrogen ion in water while bases are substances that produce hydroxide ion in water.
The pH scale is a graphic description of the hydrogen or hydroxide ion present in a sample. Since pH= -log[H^+], the higher the pH , the lower the hydrogen ion concentration and vice versa.
Similarly, pOH= -log [OH^-] , hence the more the OH^- concentration the lower the pOH.
However pH + pOH =14.
Thus the concentration of hydrogen or hydroxide ions present determines the pH of any solution.
