Thermodynamics Final Examination

What is the primary focus of thermodynamics involving energy transfer?

• Chemical reactions

• Heat, work, and energy transfer

• Gravity and magnetism

• Atomic structure

The Zeroth Law of Thermodynamics was named by:

• Isaac Newton

• Albert Einstein

• Ralph H. Fowler

• James Joule

Why is it called the "Zeroth" Law?

• It was the first law discovered

• It was too basic to be the Fourth Law

• Scientists wanted to confuse others

• It replaced the First Law

Which of the following best illustrates thermal equilibrium?

• Ice melting in warm water

• Boiling water on a stove

• A heated iron rod cooling in air

• A thermometer reading the same temperature as your body

Heat transfer occurs from:

• Cold to hot spontaneously

• Hot to cold spontaneously

• Cold to cold

• Hot to hot

What happens when two systems reach thermal equilibrium?

• They have different temperatures

• Heat transfer stops

• Heat flows indefinitely

• Energy is destroyed

What is an example of the Zeroth Law in action?

• A car engine running

• A thermometer in boiling water

• Mixing oil and water

• Heating a pot of soup

Which concept describes energy conservation in thermodynamics?

• Zeroth Law

• First Law

• Second Law

• Third Law

The formula for the First Law of Thermodynamics is:

• ΔU = Q + W

• ΔU = Q - W

• ΔU = Q/W

• ΔU = QW

What type of thermodynamic process has no heat transfer?

• Isobaric

• Isochoric

• Isothermal

• Adiabatic
