Thermodynamics Quiz

Thermodynamics

• Thermodynamics is the study of energy and its transformations.
• The First Law of Thermodynamics states the principle of conservation of energy.
• A thermodynamic property, such as pressure, describes a system.
• A system boundary separates a thermodynamic system from its surroundings.
• Work is not a state function in thermodynamics.
• A closed system allows only energy transfer across its boundary.
• Temperature is a property that measures using the zeroth law of thermodynamics.
• Work completed by a system is done on the surroundings.
• An adiabatic process has no heat transfer.
• The second law of thermodynamics states that entropy of an isolated system always increases.
• The SI unit for heat energy is the joule.
• Volume is constant in an isochoric process.
• Specific heat is the amount of heat needed to raise the temperature of one mole of a substance by one Kelvin.
• Temperature is constant in an isothermal process.
• The first law of thermodynamics relates heat, work, and internal energy.
• An isobaric process has constant pressure.
• Perpetual motion machines are impossible according to the second law of thermodynamics.
• Open systems allow both mass and energy transfer.
• Thermodynamics primarily deals with thermal systems.
• Heat is not a system property.
• Entropy measures disorder or randomness in a system.
• Temperature is not an extensive property.

Further Concepts
