Answer:
Step 1;
q = w = -0.52571 kJ, ΔS = 0.876 J/K
Step 2
q = 0, w = ΔU = -7.5 kJ, ΔH = -5.00574 kJ
Explanation:
The given parameters are;
= 100 N·m
= 327 K
= 90 N·m
Step 1
For isothermal expansion, we have;
ΔU = ΔH = 0
w = n·R·T·ln(/) = 1 × 8.314 × 600.15 × ln(90/100) = -525.71
w ≈<em> -0.52571</em> kJ
At state 1, q = w = -0.52571 kJ
ΔS = -n·R·ln(/) = -1 × 8.314 × ln(90/100) ≈ 0.876
ΔS ≈ 0.876 J/K
Step 2
q = 0 for adiabatic process
ΔU = 25×(27 - 327) = -7,500
w = ΔU = <em>-7.5 kJ</em>
ΔH = ΔU + n·R·ΔT
ΔH = -7,500 + 8.3142 × 300 = -5,005.74
ΔH = ΔU = <em>-5.00574 kJ</em>
Answer:
Cells are the simplest structures that can carry out all of the characteristics activities of life.
Explanation:
All living things are made of cells and all cells come from other cells.
Answer:
A and B
Explanation:
A: The discovery of x- rays is a scientific discovery that led to X-ray machines which is technology.
B: Finding out that massive amounts of energy can be released by splitting the nucleus of an atom was the discovery and it led to nuclear power plants.
Satellites helping scientists map the earth doesn't really have an example of science. It just says that Satellites help scientists, and satellites are technology.
Robotic machines are also technology. Robots assisting doctors in surgery is technology helping people not science influencing technology.
So A and B would be the answers.
Hope this helps :)
