Laws of Thermodynamics Quiz

What does the Zeroth Law of Thermodynamics state?

• If two bodies are in thermal equilibrium with a third body, they are also in equilibrium with each other.

• Energy cannot be created or destroyed, only transformed.

• The total entropy of an isolated system can never decrease over time.

• For every action, there is an equal and opposite reaction.

What is thermodynamics?

• A branch of chemistry that studies chemical reactions.

• The branch of physics that deals with the relationships between heat and other forms of energy.

• A field of biology that focuses on the study of living organisms.

• An area of mathematics that deals with the properties of numbers.

What is an example of convection?

• The heating of water in a pot on a stove, where warm water rises and cool water sinks.

• The melting of ice in a glass of water.

• The boiling of water in a kettle without any movement.

• The cooling of a metal rod in air.

What is the Second Law of Thermodynamics?

• The total entropy of an isolated system can never decrease over time.

• Energy can be created and destroyed in an isolated system.

• The entropy of a system can be decreased by doing work on it.

• Heat cannot spontaneously flow from a colder body to a hotter body.

What is conduction?

• Conduction is the transfer of thermal energy through direct contact between materials.

• Conduction is the process of energy transfer through electromagnetic waves.

• Conduction is the movement of particles in a gas due to temperature differences.

• Conduction is the transfer of energy through the movement of fluids.

What is an example of radiation?

• The warmth felt from the sun on your skin.

• The sound of a ringing bell.

• The taste of salt in seawater.

• The color of a rainbow.

What is radiation?

• Radiation is the transfer of thermal energy through empty space without the need for a medium.

• Radiation is the process of converting light into heat energy.

• Radiation is the movement of particles through a solid medium.

• Radiation is the emission of sound waves through air.

What is an example of conduction?

• A metal spoon getting hot when placed in a hot soup.

• A fan blowing air to cool a room.

• Ice melting in a warm drink.

• Boiling water in a kettle.

What is convection?

• Convection is the process of heat transfer through the movement of fluids (liquids or gases) where warm molecules rise and cool molecules sink.

• Convection is the transfer of heat through direct contact between materials.

• Convection is the process of heat transfer through electromagnetic waves.

• Convection is the movement of air caused by the rotation of the Earth.

What is heat?

• Heat is a form of energy that can be measured in joules.

• Heat is energy transferred between substances or systems due to a temperature difference.

• Heat is the temperature of an object measured in Celsius.

• Heat is a type of radiation that travels through space.
