Basics of Thermodynamics Quiz

What is the first law of thermodynamics?

• Energy cannot be created or destroyed, only transformed from one form to another.

• Energy can only be transformed into heat

• Energy can be destroyed completely

• Energy can be created out of nothing

Explain the second law of thermodynamics.

• Total entropy of an isolated system can never decrease over time

• The temperature of an isolated system always remains constant

• Energy can be created in an isolated system

• Entropy always decreases in an isolated system

What are the three methods of heat transfer?

• Freezing, boiling, melting

• Conduction, convection, and radiation

• Expansion, compression, evaporation

• Reflection, absorption, transmission

How does convection differ from conduction and radiation?

• Convection involves the transfer of heat through the movement of fluids.

• Convection involves the transfer of heat through chemical reactions

• Convection involves the transfer of heat through electromagnetic waves

• Convection involves the transfer of heat through solid materials

What is meant by thermal equilibrium?

• Same temperature of two or more objects or substances in contact

• Different temperature of two or more objects or substances in contact

• The transfer of heat between two objects

• The state of matter when it is neither solid nor liquid
