Thermodynamics Quiz

Study Notes

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.

A cycle's net internal energy change is zero.
Work is a path-dependent quantity.
An isothermal process maintains a constant temperature.
Absolute pressure considers vacuum.
Pressure at a depth is related to depth and liquid density.
Temperature can be expressed in different units.
Temperature difference is calculated from given temperatures.
Heat needed to raise air temperature is dependent on mass and temperature differences.
Density is pressure- and temperature-dependent.
Atmospheric pressure has equivalency with various unit systems.
The ideal gas constant is a universal constant.
Boyle's Law shows an inverse relationship between pressure and volume.
Charles' Law demonstrates a direct relationship between volume and temperature.
Avogadro's Law relates volume to the number of moles.
Ideal gas interactions are negligible.
A change in pressure affects volume in a gas.
Gay-Lussac's Law relates temperature.
Expanding gases increase in volume with greater moles.
A doubling of volume halves the pressure in an ideal gas under constant temperature.
Examples of kinetic, potential, and mechanical energy are provided.
Thermal energy is associated with temperature changes.
Spring energy is elastic potential energy.
