Kokonaislämpö, sometimes translated as total heat or enthalpy, is a thermodynamic concept used to describe the energy content of a substance. In a broader sense, it refers to the sum of the internal energy of a system and the product of its pressure and volume. This quantity is particularly relevant in processes where energy is transferred, such as in heat exchange or phase changes.

The enthalpy of a substance can be understood as the heat absorbed or released during a process occurring at constant pressure. It encompasses both the internal energy, which is the kinetic and potential energy of the molecules within the substance, and the work done by or on the system to expand or contract against its surroundings. Therefore, changes in enthalpy are often directly measurable as heat flow in many practical applications.

In meteorology, "kokonaislämpö" can refer to the total heat content of the atmosphere. This includes the sensible heat, which is the heat we can feel and measure with a thermometer, and the latent heat, which is the energy stored or released during phase transitions of water, such as evaporation or condensation. Understanding the distribution and movement of total heat in the atmosphere is crucial for predicting weather patterns and the development of storms.

The concept of kokonaislämpö is a fundamental principle in thermodynamics and has wide-ranging applications in fields such as engineering, chemistry, and atmospheric science, providing a comprehensive measure of a system's energy state.
