Quiz on Thermodynamics

What does the first law of thermodynamics state?

• Energy cannot be created or destroyed.

• Energy can be created and destroyed.

• Energy can only be transformed.

• Energy is always lost in a system.

What does the second law of thermodynamics imply about entropy?

• Entropy decreases in a closed system.

• Entropy remains constant in a closed system.

• Entropy increases in a closed system.

• Entropy can be created or destroyed.

What is entropy a measure of?

• Order and organization in a system.

• Disorder and randomness in a system.

• Energy and work in a system.

• Temperature and pressure in a system.

What happens to entropy as the temperature approaches absolute zero?

• Entropy approaches a maximum.

• Entropy approaches a minimum.

• Entropy remains constant.

• Entropy becomes negative.

What is a thermodynamic cycle?

• A process that increases energy.

• A sequence of processes returning to the original state.

• A method to destroy energy.

• A way to create energy.

How does heat transfer occur according to the laws of thermodynamics?

• Only through radiation.

• Only through conduction.

• Only through convection.

• Through conduction, convection, and radiation.

What is the relationship between temperature and kinetic energy in thermodynamics?

• Temperature is a measure of potential energy.

• Higher temperature means higher kinetic energy.

• Higher temperature means lower kinetic energy.

• Temperature and kinetic energy are unrelated.
