Study Notes

Primary Focus of Thermodynamics

Thermodynamics primarily studies the relationships between heat, work, temperature, and energy.
It examines how these quantities interact and transform in various systems.

First Law of Thermodynamics

The first law states that energy cannot be created or destroyed; it can only change forms.
This principle emphasizes the conservation of energy in isolated systems.

Second Law of Thermodynamics

The second law implies that energy efficiency in processes is inherently limited.
It introduces the concept of entropy, indicating that energy transformations tend to increase disorder in a system, reducing the efficiency of energy use.

Specific Heat Capacity

Specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius (or Kelvin).
It varies between materials and is crucial for understanding temperature changes during heat transfer.

Thermal Equilibrium

Thermal equilibrium is defined as a state in which two or more systems have reached the same temperature and no heat flows between them.
At this state, the energy exchange through heat is balanced, resulting in stability in thermal conditions.
