Constant amount of ideal gas is kept inside a cylinder by a piston. The piston is locked in to position, it is not allowed to move. The gas is then heated up. Compare the initial (i) and the final (f) physical quantities of the gas to each other.

(The fill in the blank options are greater than, less than, or equal too).

The volume Vf is ... Vi.

The temperature Tf is ... Ti.

The internal energy Uf is ... Ui.

The entropy Sf is ... Si.

The pressure pf is ... pi.

An insulated cylinder/piston contains ammonia at 1000 kPa, 120 ◦C. The piston is moved, expanding the ammonia in a reversible adiabatic process until the temperature is 0.0 ◦C. During the process, 200 kJ of work is given out by the ammonia. Find the following:
(A) Entropy of final state

  
QUESTION 2

(B) Pressure of final state
  
QUESTION 3

(C) Mass of ammonia

  
QUESTION 4

(D) Volume of initial state

You and a friend, along with an eccentric rich probabilist, are observing a Poisson process whose arrival rate is λ = .5 per hour. The probabilist offers to pay you $100 if there is at least one arrival between noon and 2pm, and also offers to pay your friend $100 if there is at least one arrival between 1pm and 3pm.

a. What is the probability that either you or your friend, or both, gets $100?

b. What is the probability that one of you wins $100, but not both?

Consider a Poisson process with arrival rate λ per minute. Given that there were three arrivals in the first 2 minutes, find the probability that there were k arrivals in the first minute; do this for k = 0, 1, 2, and 3.

Given that P(A) = .4, P(A ∩ B) = .1, and P((A ∪ B) c ) = .2, find P(B).

Given an array A[0 … n-1], where each element of the array represent a vote in the election. Assume that each vote is given as an integer representing the ID of the chosen candidate. Can you determine who wins the election? What is the complexity of your solution? Hint: it is similar to finding the element that is repeated the maximum number of times.
