Thermodynamics Quiz

What does the Zeroth Law of Thermodynamics establish?

• Concept of entropy

• Law of energy conservation

• Concept of temperature

• Heat cannot flow from cold to hot

Which thermodynamic process occurs at constant volume?

• Isobaric

• Isothermal

• Isochoric

• Adiabatic

In spray drying of milk, what type of thermodynamic process is it?

• Isobaric

• Adiabatic

• Isochoric

• Isothermal

Which system exchanges energy but not matter?

• Open

• Closed

• Isolated

• Cyclic

What is entropy a measure of?

• Energy conservation

• Temperature difference

• Randomness or disorder

• Heat content

Which cycle is used in food plants with steam turbines?

• Carnot Cycle

• Kelvin Cycle

• Rankine Cycle

• Otto Cycle

During yogurt fermentation at a constant temperature, which process occurs?

• Adiabatic

• Isochoric

• Isothermal

• Isobaric

Which property is independent of mass?

• Volume

• Energy

• Temperature

• Enthalpy

The second law of thermodynamics implies no process is 100% efficient.

Enthalpy changes during phase transitions always raise temperature.
