Thermodynamics and Energy Changes

Front

What does the PV diagram for an adiabatic process resemble?

Back

The PV diagram for an adiabatic process looks similar to that of an isothermal process.

Front

If work is done on a system, how is the work classified?

Back

The work done is classified as Negative.

Front

What type of thermodynamic system is characterized by no exchange of matter or energy with its surroundings?

Back

An isolated system.

Front

What does the variable 'P' represent in thermodynamics?

Back

'P' represents pressure.

Front

If a system does 300 J of work while absorbing 800 J of heat, what is the change in internal energy?

Back

The change in internal energy is 500 J.

Front

Define an isothermal process.

Back

An isothermal process is one in which the temperature remains constant.

Front

What is the first law of thermodynamics?

Back

The first law of thermodynamics states that energy cannot be created or destroyed, only transformed.

Front

What is an open system in thermodynamics?

Back

An open system can exchange both energy and matter with its surroundings.

Front

What is an example of an isobaric process?

Back

An example of an isobaric process is boiling water at a constant pressure.

Front

What does the term 'enthalpy' refer to?

Back

Enthalpy is a measure of the total energy of a thermodynamic system, including internal energy and the energy required to displace its environment.
