Question

1. Consider the cycle shown in the figure below. Find the net heat energy transferred to the system during one cycle.

2. A balloon contains forming gas (i.e. a mixture of 95% nitrogen and 5% hydrogen that is used in certain industrial processes because it provides hydrogen at concentrations that are not explosive) at STP.

   (a) What is the average kinetic energy of each type of molecule?

(b) What is the rms speed of each of the two types of molecule?

(c) What is the average force applied to the sides of the balloon by each of the two types of molecule?

3. The 250 litre cylinder of a steam train contains superheated steam at 300 degrees celcius and 10 atm. Assuming CV =7R/2 calculate:

(a) the specific heat of the steam in SI units.

(b) the number of moles of the steam in the cylinder.

(c) the amount of energy released as the steam cools down to room temperature if the piston is free to move.

(d) the amount of energy released as the steam cools down to room temperature if the piston is held in a fixed position.

4. A solid copper rod is joined to a solid iron rod of the same length and diameter. The free end of the copper rod is inserted into boiling water and the free end of the iron rod is inserted into an ice bucket. When the temperature profile along the rod reaches steady state, what is the temperature at the junction?
