Untitled Flashcards

Front

Temperature

Back

Degree of hotness or the coldness of a body

Front

Thermal equilibrium

Back

Condition where there is no net flow of heat energy between the bodies

Front

Internal energy of solids

Back

Average molecular vibrational kinetic energy ( due to the transfer of heat energy and rise in temperature)+ Intermolecular potential energy (due to the strong bonds between the particles)

Greatest P.E., least K.E compared to fluids

Front

Internal energy of fluids. Ex: Liquids and Gases

Back

translational kinetic energy and Intermolecular potential energy due to the spacing between the particles

More K.E, and least P.E compared to solids

Front

Internal energy of gases

Ex: Ideal gas and its theory

Back

Translational and Rotational random K.E only, which is directly proportional to temperature (T).

Negligible P.E due to weak intermolecular forces and increase int he brownian motion(Random) of particles

Front

Absolute Zero

Back

-273 degrees or 0 K

Significance: Everything stops moving.

Systems becomes more orderly state

Condition to study Superconductivity, Superfluidity

Theory assumption

practically impossible

explains bose- Einstien condensates(ultra cold atoms forming quantum matter)

Front

very weak intermolecular force

Back

gases
