"The first law of thermodynamics is a formulation of the law of conservation of energy in the context of thermodynamic processes."
Introduction and interpretation of the first law of thermodynamics, including energy conservation and the relationship between heat and work.
Energy: Understanding the various forms of energy and their interconversion is crucial to understanding the First Law of Thermodynamics.
Work: Learn about the concept of work, including its definition, formulae, and units of measurement. This includes understanding the different types of work, such as work done by a gas during expansion or contraction.
Heat: The transfer of heat energy is essential to the First Law of Thermodynamics. Learn about the different modes of heat transfer, including conduction, convection, and radiation.
Internal Energy: The internal energy of a system is the sum of all its microscopic kinetic and potential energies. Understanding how to calculate and measure internal energy is necessary when studying the First Law of Thermodynamics.
Enthalpy: Enthalpy is a measure of the heat content of a system at constant pressure. Learn about how to calculate enthalpy, and its connection to the First Law of Thermodynamics.
Conservation of Energy: The First Law of Thermodynamics is based on the principle of conservation of energy, which states that energy cannot be created or destroyed. Understanding this principle is critical to comprehending the laws of thermodynamics.
Heat Capacity: The heat capacity of a substance is the amount of heat required to increase its temperature by one degree. Understanding heat capacity is necessary when studying the behavior of thermodynamic systems.
Thermodynamic Processes: Learn about the different types of thermodynamic processes, such as adiabatic, isothermal, and isobaric. Understanding these processes is crucial in applying the First Law of Thermodynamics to real-world scenarios.
Heat Engines: A heat engine is a device that converts thermal energy into useful work. Learn about the efficiency of heat engines, and how they relate to the First Law of Thermodynamics.
Entropy: Entropy is a measure of the randomness or disorder of a system. Understanding entropy and its relationship to the Second Law of Thermodynamics is essential when studying thermodynamics.
Internal Energy: The First Law of Thermodynamics states that the internal energy of a system is constant. It means that the energy that goes into a system should be equal to the energy that goes out of it.
Work Energy: This principle of the First Law of Thermodynamics says that the amount of work done is equal to the energy transferred.
Heat Energy: The heat energy principle of the First Law of Thermodynamics states that the total amount of heat energy supplied to a system is equal to the internal energy of the system plus the work done.
Energy Conservation: The First Law of Thermodynamics emphasizes the energy conservation principle, meaning that energy cannot be created or destroyed; it can only be transformed from one form to another.
Mass Conservation: The First Law of Thermodynamics also emphasizes mass conservation principle meaning mass cannot be created or destroyed, only transferred from one form to another.
Adiabatic Processes: Adiabatic processes are those processes that take place without any heat transfer between the system and its surroundings. The First Law of Thermodynamics states that the internal energy of a system undergoing an adiabatic process remains constant.
Enthalpy: Enthalpy is an important property in thermodynamics that is used to describe the heat energy of a system. The First Law of Thermodynamics states that the change in enthalpy of a system is equal to the heat energy supplied to it.
"It distinguishes in principle two forms of energy transfer, heat and thermodynamic work for a system of a constant amount of matter."
"The law defines the internal energy of a system, an extensive property for taking account of the balance of these energies in the system."
"Energy cannot be created or destroyed, but it can be transformed from one form to another."
"In an isolated system, the sum of all forms of energy is constant."
"An equivalent statement is that perpetual motion machines of the first kind are impossible."
"Work done by a system on its surroundings requires that the system's internal energy be consumed."
"The amount of internal energy lost by that work must be resupplied as heat by an external energy source or as work by an external machine acting on the system to sustain the work of the system continuously."
"The ideal isolated system, of which the entire universe is an example, is often only used as a model."
"Many systems in practical applications require the consideration of internal chemical or nuclear reactions, as well as transfers of matter into or out of the system."
"For such considerations, thermodynamics also defines the concept of open systems, closed systems, and other types."
