FAQs (Frequently Asked Questions)

A thermodynamic system is a system that is delimited from the surroundings by hypothetical or real boundaries. The part of the universe in which observations are made is a thermodynamic system. The system has a boundary and all that is beyond the system, i.e. the remaining universe, is called surroundings. The system and surroundings can have an exchange of mass and energy. 

There are three types of systems discussed in this chapter;

Open System: A system that is able to exchange both energy and matter with the area beyond the boundary (its surroundings) is said to be an open system.

Closed System: A system that can exchange energy but cannot exchange matter with its surroundings is called a closed system.

Isolated System: A system that cannot exchange energy or matter with its surroundings is called an isolated system. 

The branches of thermodynamics are;

Classical Thermodynamics

In this branch of Thermodynamics, a macroscopic approach is used to analyse the behaviour of matter. Pressure and temperature units being taken into consideration help in calculating other properties and in predicting the characteristics of matter (which is undergoing the process).

Statistical Thermodynamics

Every molecule is under the spotlight in statistical thermodynamics. This means that every molecule’s properties and how they interact is taken into consideration to determine the behaviour of a collection of molecules.

Chemical Thermodynamics

Chemical thermodynamics is the study of the interrelation of work and heat during chemical reactions as well as changes in states.

Equilibrium Thermodynamics

The study of energy and matter transformations as they approach the state of equilibrium is called equilibrium thermodynamics.

The heat of a reaction caused because of a chemical reaction that takes place when pressure is constant is called Enthalpy. The amount of energy per mole in a reaction is calculated using thermodynamics measurement. Volume, internal energy, and pressure are used to derive Enthalpy. 

H= E+PV 

Where H= Enthalpy, P= Pressure, V= Volume, and E= Internal Energy.

The heat of reaction in a chemical process is calculated using heat reaction. The flow of heat in a calorimeter can be calculated using a change in enthalpy. This is utilised to evaluate Joule Thomson Expansion or the throttling process. Additionally, the minimum power used in a compressor is utilised to measure enthalpy. 

The thermodynamic process includes the movement of heat energy within a system. The four types of thermodynamic cycles are Isobaric, Isothermal, Isochoric, and Adiabatic.

Isobaric: This is a process that sees no change in pressure. 

Isothermal: This is a process that does not see any change in temperature.

Isochoric: In this process, there is no change in volume and the system remains constant.

Adiabatic: Here the heat does not go in or out of the system. 

If all the thermodynamic processes stay constant with passing time, a system is said to be in thermodynamic equilibrium (as per thermodynamic concepts). All properties of a system have fixed values at a given state, hence, a change in even one property can change the system’s state into a different one altogether. A system in equilibrium sees no change occur in the value of properties when it is isolated from its surroundings. 

When it is observed that at any point in time, there is no change in pressure, it is called mechanical equilibrium. 

Chemical equilibrium occurs when a system’s chemical composition does not vary with time. 

When the entire system observes temperature being constant, it is called thermal equilibrium. 

When the mass of each phase in a two-phase system reaches an equilibrium level, it is called phase equilibrium. 

When a thermodynamic system is in mechanical, chemical, and thermal equilibrium, and the relevant parameters cease changing with time, the system is believed to be in thermodynamic equilibrium.
