Introduction to Thermodynamics

An open system is one in which

• Heat and work cross the boundary, but the mass does not

• Mass crosses the boundary, but the heat and work do not

• Heat, work and mass cross the boundary

• None of heat, work and mass cross the boundary

Which of the following is an intensive property of a thermodynamics systems?

• Volume

• Temperature

• Mass

• Energy

Which of the following is the basis of temperature measurement?

• Zeroth law of thermodynamics

• First law of thermodynamics

• Second law of thermodynamics

• Third law of thermodynamics

The absolute zero pressure will be

• When molecular momentum of the system becomes zero

• at sea level

• at a temperature of -273.15 K

• under vacuum conditions

The standard fixed point of the thermometry is the

• ice point

• triple point of water

• boiling point water

• sulphur point

Most of real processes are

• quasi-static

• non-quasi-statics

• adiabatic

• isothermal
