Thermodynamics - answer The study of the effects of work, heat flow, and energy on a
system; Movement of thermal energy
Thermal Energy - answer kinetic energy in transit from one object to another due to
temperature difference. (Joules)
Temperature - answer the average kinetic energy of particles in an object—not the total
amount of kinetic energy particles.
Absolute Zero - answeroccurs when all kinetic energy is removed from a object
Thermal Equilibrium - answerobtained when touching objects within a system reach the
same temperature;reached, the system loses its ability to do work.
Zeroth Law of thermodynamics - answerIf two systems are separately found to be in
thermal equilibrium with a third system, the first two systems are in thermal equilibrium
with each other.
thermal energy transfer - answerconvection; conduction; radiation
1st Law of Thermodynamics - answerLaw of energy conservation applied to a thermal
system;Thermal energy can change form and location, but it cannot be created or
destroyed.
Thermal energy can be increased within a system by adding thermal energy (heat) or by
performing work in a system.
Second Law of Thermodynamics - answerThermal energy flows from hot to cold
Entropy - answeris the measure of how evenly distributed heat is within a system.
Convection - answerThe transfer of thermal energy by movement of fluid (liquid or gas)
Conduction - answerThe transfer of thermal energy within an object or between objects
from molecule to molecule
Coefficient of Heat Conductivity
(U-value) - answerThe measure of a material's ability to conduct heat
