The First Law of Thermodynamics

Front

What does the First Law of Thermodynamics state?

Back

The First Law of Thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What does 'Q' represent in the First Law of Thermodynamics?

Back

In the First Law of Thermodynamics, 'Q' represents the energy transferred as heat.

Front

What is an Isothermal process?

Back

An Isothermal process is a thermodynamic process in which the temperature remains constant, and heat transferred is completely used for work.

Front

What is an Isovolumetric process?

Back

An Isovolumetric process is a thermodynamic process where no work is done on or by the system, and the volume remains constant.

Front

What is an Adiabatic process?

Back

An Adiabatic process is a thermodynamic process in which no heat is transferred to or from the system.

Front

What is an Isolated System?

Back

An Isolated System is a physical system that does not interact with its surroundings, resulting in no exchange of energy or matter.

Front

What is the formula for the First Law of Thermodynamics?

Back

The formula is ΔU = Q - W, where ΔU is the change in internal energy, Q is the heat added to the system, and W is the work done by the system.

Front

What happens to internal energy in an Isolated System?

Back

In an Isolated System, there is no change in internal energy as there is no heat or work exchange with the surroundings.

Front

What is the significance of the First Law of Thermodynamics in energy conservation?

Back

The First Law of Thermodynamics emphasizes the principle of conservation of energy, stating that the total energy of an isolated system remains constant.

Front

How does an Adiabatic process differ from an Isothermal process?

Back

In an Adiabatic process, no heat is exchanged, while in an Isothermal process, heat is exchanged but temperature remains constant.
