Thermodynamics Flashcards

Front

Isothermal

Back

A change that occurs at constant temperature.

Front

Molar Heat Capacity

Back

The amount of heat needed to change a mole of a substance by 1°C.

Front

Internal Energy Change (ΔE)

Back

Depends only on the initial and final state, not the path taken.

Front

Electrical Work in Chemistry

Back

Work done through a wire.

Front

PV Work

Back

Work done as a gas expands, calculated as PΔV.

Front

Units of Work

Back

Units of work are units of energy. Doing work increases the potential energy of the system.

Front

Work Calculation in Chemical Reactions

Back

Work can be calculated as ΔnRT for reactions where the number of moles of gas changes.

Front

Work is not a state function in chemical thermodynamics.

Back

It depends on how you do the work.

Front

Reversible processes.

Back

Theoretical maximum work is achieved if steps are reversible.

Front

Work (PΔV) significance.

Back

Generally insignificant unless moles of gas change.
