Thermodynamics Test 2

A definite area or space where some thermodynamic process takes place is known as 

• Thermodynamic system 

• thermodynamic cycle 

•   thermodynamic process     

•   thermodynamic law

An open system is one in which                                                                              

• heat and work cross the boundary of the system, but the mass of the working substance does not

• mass of working substance crosses the boundary of the system but the heat and work do not

• both the heat and work as well as mass of the working substances cross the boundary of the system

• neither the heat and work nor the mass of the working substances cross the boundary of the system.

An isolated system                                                                                                  

• is a specified region where transfer of energy and/or mass take place

• is a region of constant mass and only energy is allowed to cross the boundaries

• cannot transfer either energy or mass to or from the surroundings

• is one in which mass within the system is not necessarily constant

In an extensive property of a thermodynamic system                                                         

• extensive heat is transferred

• extensive work is done  

• extensive energy is utilised 

• all of the above  

• none of the above

Which of the following is an intensive property of a thermodynamic system ?        

• Volume 

• Temperature 

• Mass  

• Energy

Which of the following is the extensive property of a thermodynamic system ?        

• Pressure   

• Volume  

• Temperature   

• Density

When two bodies are in thermal equilibrium with a third body they are also in thermal equilibrium with each other. This statement is called             

• Zeroth law of thermodynamics 

• First law of thermodynamics  

• Second law of thermodynamics

• Kelvin Planck’s law.

The temperature at which the volume of a gas becomes zero is called                     

• absolute scale of temperature   

• Absolute zero temperature  

• absolute temperature  

• none of the above.

Which of the following is correct?                                                                            

• Absolute pressure = gauge pressure + atmospheric pressure

• Gauge pressure = absolute pressure + atmospheric pressure

• Atmospheric pressure = absolute pressure + gauge pressure

• Absolute pressure = gauge pressure – atmospheric pressure.

The amount of heat required to raise the temperature of 1 kg of water through 1°C is called 

• specific heat at constant volume   

• specific heat at constant pressure  

• kilo calorie  

• none of the above.
