Thermodynamics Vocabulary Quiz

The thermal transfer of energy by electromagnetic waves.

• Convection

• Radiation

• Thermal Conduction

• Temperature

The state in which the required thermal energy transfer between two objects are equal and the objects are at the same temperature.

• First Law of Thermodynamics

• Heat of Vaporization

• Thermal Equilibrium

• Second Law of Thermodynamics

The amount of thermal energy required to change 1 kg of a substance from a solid state to a liquid state at its melting point.

• Specific Heat

• Heat of Fusion

• Convection

• Heat of Vaporization

A measure of the energy dispersal in a system.

• Convection

• Temperature

• Entropy

• Radiation

The amount of energy that must be added to a material to raise the temperature of a unit mass by one temperature unit; measured in J/kg.K.

• Heat of Vaporization

• Specific Heat

• Convection

• Heat of Fusion

A device that continuously converts thermal energy to mechanical energy; requires a high temperature thermal energy source, a low temperature receptacle (a sink), and a way to convert the thermal energy into work.

• Heat Engine

• Heat of Fusion

• Convection

• Temperature

A transfer of thermal energy, which occurs spontaneously from a warmer object to a cooler object. Represented by a capital Q.

• Specific Heat

• Heat of Fusion

• Heat

• Heat of Vaporization

The transfer of thermal energy when particles collide

• Heat of Fusion

• Radiation

• Heat of Vaporization

• Thermal Conduction

States that the change in thermal energy of a system is equal to the heat that is added to the system, minus the work done by the system.

• Second Law of Thermodynamics

• First Law of Thermodynamics

• Thermal Equilibrium

• Heat of Vaporization

A measure of the average kinetic energy of the particles in a system

• Entropy

• Heat Engine

• Temperature
