Thankyou, Nicolas Léonard Sadi Carnot is often described as the “Father of Thermodynamics.”. Efficiency of Carnot engine:- Efficiency η of an engine is defined as the ratio between useful heat (heat converted into work) to the total heat supplied to the engine. The distinction between mechanics and thermodynamics is worth noting. In this state, the movement of molecules is further restricted and the entropy of the system reduces more. Michael Fowler, UVa. THERMODYNAMICS It is the branch of chemistry which deals with the energy changes taking place during physical and chemical changes. Physics. Different types of vehicles such as planes, trucks and ships work on the basis of the 2nd law of thermodynamics. Thermodynamics deals with the concepts of heat and temperature and the inter-conversion of heat and other forms of energy. Example:- All isothermal and adiabatic process when allowed to proceed slowly, are reversible, provided there is no loss of energy against any type of resistance. → Enthalpy is the measurement of energy in a thermodynamic system. branch of physics which is concerned with the relationship between other forms of energy and heat Privacy Policy | CBSE quick revision note for class-11 Physics, Chemistry, Maths, Biology and other subject are very helpful to revise the whole syllabus during exam days. its direction can be reversed at any moment. (b) Efficiency:- Efficiency η of an engine is defined as the fraction of total heat, supplied to the engine which is converted into work. Intensive properties are properties that do not depend on the quantity of matter. The thermometer is also in equilibrium with cup B. (a) Equation of adiabatic change in terms of, (b) Equation of adiabatic change in terms of, = (Number of moles of gaseous products - Number of moles of gaseous reactants), Structural Organisation in Plants and Animals, French Southern and Antarctic Lands (+262), United state Miscellaneous Pacific Islands (+1). Thermodynamics deals with energy transfer processes. Without the ability of a system to use energy within the system to do work — the heart of thermodynamics — there would be nothing for physicists to study. If a room is not tidied or cleaned, it invariably becomes more messy and disorderly with time. Basically, this means that if system A is in thermal equilibrium with system C and system B is also in equilibrium with system C, then system A and B are also in thermal equilibrium with each other. (d) Adiabatic process:- The process in which change in pressure and volume and temperature takes place without any heat entering or leaving the system is called adiabatic change.

FIRST LAW OF THERMODYNAMICS First law of thermodynamics gives a relationship between heat, work and internal energy. Many individuals take this statement lightly and for granted, but it has an extensive impact and consequence. As the sweat absorbs more heat, it evaporates from your body, becoming more disordered and transferring heat to the air, which heats up the air temperature of the room. Free Webinar on the Internet of Things (IOT)    There are several copies of the second edition in the library. (a) Specific heat capacity at constant volume (cv):- Specific heat capacity at constant volume is defined as the amount of heat required to raise the temperature of 1 g of the gas through 1ºC keeping volume of the gas constant. Here you can read Chapter 12 of Class 11 Physics NCERT Book. If one decreases the temperature below 100 °C, the steam gets converted to water, where the movement of molecules is restricted, decreasing the entropy of water. Equation of state for an ideal gas is PV = RT. The four laws of thermodynamics govern the behaviour of these quantities and provide a quantitative description. Welcome! mole: 1 mole of a substance contains Avogadro's number (N = 6.02E23) of molecules. Based on the system constraints, such as temperature and pressure, different potentials are used. Thermal energy is the energy that comes from heat. School Tie-up | We have listed a few of these applications below: → In simple terms, thermodynamics deals with the transfer of energy from one form to another. Thermodynamics is a macroscopic science. The quantity of enthalpy equals the total content of heat of a system, equivalent to the system’s internal energy plus the product of volume and pressure. It should also be noted that Thermodynamics is a macroscopic science. Thermodynamics is involved in the study of different types of power plants such as nuclear power plants, thermal power plants. This is one of over 2,200 courses on OCW. This is explained by the First law of thermodynamics.

The entropy of the universe only increases and never decreases. Without the ability of a system to use energy within the system to do work — the heart of thermodynamics — there would be nothing for physicists to study. These thermodynamic laws represent how these quantities behave under various circumstances. First law of thermodynamics, also known as the law of conservation of energy states that energy can neither be created nor destroyed, but it can be changed from one form to another.
