Chapter 3: Evaluating Properties

Vocabulary flashcards covering key concepts from the lecture on evaluating properties in thermodynamics.

Enthalpy

The sum of the internal energy and the product of pressure and volume.

Specific Internal Energy (u)

The internal energy per unit mass.

Specific Enthalpy (h)

The enthalpy per unit mass.

Molar Specific Enthalpy

Enthalpy per mole of a substance.

Saturation State

The condition where a liquid and its vapor coexist in equilibrium.

Quality (x)

The ratio of the mass of vapor to the total mass of a liquid-vapor mixture.

Energy Balance

An equation that accounts for the energy entering, leaving, and changing within a system.

Specific Heat (C_v)

The amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius at constant volume.

Specific Heat (C_p)

The amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius at constant pressure.

Compressible Substance

A substance whose volume can change significantly with pressure.

Interpolate

To estimate values within the range of a discrete set of known data points.

Work (W)

Energy transfer resulting from a force applied over a distance.

Heat Transfer (Q)

Energy transferred between physical systems due to temperature difference.

Two-Phase Liquid-Vapor Mixture

A state where both liquid and vapor phases are present in a thermodynamic system.

Superheated Vapor

A state of vapor that is at a temperature higher than its boiling point at a given pressure.
