MCQ ~ Thermodynamics (3)

1. When a gas is heated at constant volume

• Its temperature will increase
• Its pressure will increase
• Both temperature and pressure will increase
• Neither temperature nor pressure will increase.

2. The heating of a gas at constant pressure is governed by

• Boyle's law
• Charle's law
• Gay-Lussac law
• Joules law

3. A process, in which the gas is heated or expanded in such a way that the product of its pressure and volume remains constant, is called

• Isothermal process
• Isobaric process
• Adiabatic process
• Polytropic process

4. The hyperbolic process is governed by

• Boyle's law
• Charle's law
• Gay-Lussac law
• Joule's law

5. The heating of gas at constant ............. is governed by Boyle's law.

• Volume
• Pressure
• Temperature

6. In an Isothermal process.

• Internal energy increases
• Internal energy decreases
• There is no change in internal energy
• Internal energy first decreases and then increase.
  

7. An Adiabatic process is one in which

• No heat enters or leaves the gas
• The temperature of the gas changes
• The change in internal energy is equal to the workdone
• All of the above
  

8. The workdone in a free expansion process is

• Zero
• Minimum
• Maximum
• Positive 

9. In a steady flow process,

• The mass flow rate is constant
• The heat transfer rate is constant
• The work transfer rate is constant
• All of the above

10. The throttling process is a

• Non-flow process
• Steady flow process
• Non-Steady flow process
