A closed thermodynamic system consists of a stone with a mass of 5 kg and a bucket containing 10 m3 of water. The entire system is at the same temperature with the surroundings. The stone is initially at rest 25 m above the water. The stone falls into the water. No water is lost from the bucket. What is the change in a. Internal energy of the system b. Work done by the system c. Heat loss by the system

Solid water (ice) is slowly warmed from a very low temperature. Part A What minimum external pressure p1 must be applied to the solid if a melting phase transition is to be observed? p1 = ? Pa Part B Above a certain maximum pressure p2, no boiling transition is observed. What is this pressure? p2 = ? Pa

a)
b)
Chlorine will have a lower pressure than flourine under the same conditions: O a larger a term will result in a higher pressure. van der Waals b term for chlorine is much larger than that of flourine. 0 van der Waals a term for chlorine is much larger than that of flourine. O a larger b term will result in a higher pressure. o the b term has a larger effect on pressure than does the a term....

6. A spring-mass system is oscillating under no external force, with a damping constant equal to 2 and spring constant equal to 1. If at t = 0 we release (x'(0) = 0) the mass from a stretched position at a displacement of x(0) = 3. Write down the modelling ODE and solve it to find the solution. What will happen eventually to the system? Is it overdamped or undedamped? Will it oscillate?

A piston containing 0.75 moles of a perfect gas at 25 degrees C
is moved isothermally from a starting volume of 8.305 L.
Calculate the work in joules if the piston is moved irreversibly
against a constant external pressure of 4.100 atm. We weren't
giving final volume so I am unsure of what to do. I tried to use
P1V1 = P2V2 because the final pressure is equal to external
pressure in an irreversible process. But then my final volume...
