CHXI06:THERMODYNAMICS

Which of the given properties depends on the manner in which a change is brought about? I.\(\Delta \mathrm{E} \quad\) II. q III. W
1 Only I
2 II and I
3 II and III
4 Only III
Explanation:
\(\Delta \mathrm{E}\) is a state variable, i.e. it is independent of the manner in which change is brought about while \(\mathrm{q}\) heat) and \(\mathrm{W}\) (work done) are path dependent, i.e. path functions.

The state of a gas can be described by quoting the relationship between
1 pressure, volume, temperature
2 temperature, amount, pressure
3 amount, volume, temperature
4 pressure, volume, temperature, amount
Explanation:
State of a system can be described by state functions or state variables which are pressure, volume, temperature and amount of the gas \(\mathrm{(\mathrm{PV}=\mathrm{nRT})}\)

Which of the following statements is correct?
1 The presence of reacting species in a covered beaker is an example of open system.
2 There is an exchange of energy as well as matter between the system and the surroundings in a closed system.
3 The presence of reactants in a closed vessel made up of copper is an example of a closed system.
4 The presence of reactants in a thermos flask or any other closed insulated vessel is an example of a closed system.
Explanation:
For a closed vessel made up of copper, no matter can be exchanged between the system and the surroundings but energy exchange can occur through its walls.

Which of the following is closed system?
1 Jet engine
2 Tea placed in a steel kettle
3 Rocket engine during propulsion
4 Pressure cooker
Explanation:
Closed system only allows energy to be exchanged with the surroundings but not mass. Tea in the steel kettle loses heat over time.
