Answer:
Hi
Final temperature = 250.11 °C
Final volume = 0,1 m3.
Process work = 0
Explanation:
The specific volume in the initial state is: v = 0.1m3/2 kg = 0.05 m3/kg.
This volume is located between the volumes as saturated liquid and saturated steam at 20 °C. For this reason the water is initially in a liquid vapor mixture. As the piston was blocked the volume remains constant and the process is isometric, also known as isocoric process, so the final temperature will be the water temperature at a saturated steam of v=0.05m3/kg, which is obtained by using steam tables for water, by linear interpolation. As follows, using table A-4 of the Cengel book 7th Edition:
v=0.05 m3/kg
v1=0.057061 m3/kg
T1=242.56°C
v2=0.049779 m3/kg
T2=250.35°C
T=
The process work is zero because there is no change in volume during heating:
W=PxΔv=Px0=0
where
W=process work
P=pressure
Δv=change of volume, is zero because the piston was blocked so the volume remains constant.
I need pictures or something
Answer:
I think it's 2 the photo is hard to tell what they are exactly talking about.
The answer is a Viscosity because it describes the internal friction of a moving liquid
<span>Correct Answer: D) 6CO2 + 6H20 → C6H12O6 + 6O2</span>
The reactants are Carbon Dioxide (CO2) and Water (H2O) and the products are Glucose (C6H12O6) and Oxygen gas (O2).
In a balanced chemical equation, the number of atoms of each element are same on both left and right hand side of the equation.
In the given options, option D gives the balanced chemical equation and mentions the reactants and products on correct sides of the equation. So the correct answer is Option D
