Can you please help me with these 5 problems!!! please and thank you Question 1 A mass of 5 kilograms of carbon dioxide (CO2) in a piston-cylinder assembly undergoes two processes in series from an initial state where p1 = 2.4 MPa, T1 = 260°C: Process 1–2: Constant-temperature expansion until the volume is twice the initial volume. Process 2–3: Constant-volume heating until the pressure is again 2.4 MPa. Assuming ideal gas behavior, determine the overall work, in kJ. ____________________________________________________________ Nitrogen...

please do both and make sure it's correct. I really need help
and i have gotten the wrong answer twice.
When gas expands in a cylinder with radius r, the pressure P at any given time is a function of the volume V: P = P(V). The force exerted by the gas on the piston (see the figure) is the product of the pressure and the area: F = ner2p. The work done by the gas when the volume expands...
can you help me figure out the following:
part a: Calculate the specific gravity for aluminum and for
brass.
part b: Calculate the specific gravity for cork.
part c: Calculate the specific gravity of the isopropyl
alcohol.
Experiment 9 Specific Gravity (Archimedes Principle) Read the Theory section on pages 9-2 & 9-3. Specific gravity is defined as the density (mass per unit volume) of a substance relative to the density of (liquid) water: s p/po, where pe is the density...
