What is Adiabatic Index? The adiabatic index, also known as the ratio of specific heats or the heat capacity ratio, is a thermodynamic property that describes how a substance’s internal energy changes in response to changes in temperature and pressure without the exchange of heat with its surroundings. It is denoted by the symbol “γ” …

What is Adiabatic Process? An adiabatic process is a thermodynamic process in which no heat is exchanged with the surroundings. In other words, during an adiabatic process, the system is isolated, and there is no heat transfer into or out of the system. The term “adiabatic” is derived from the Greek words “a,” meaning “not,” …

What is Isochoric or Constant Volume Process An isochoric process, also known as a constant volume process, is a thermodynamic process during which the volume of the system remains constant. In other words, the system undergoes changes in other properties, such as pressure, temperature, or internal energy, while the volume remains unchanged. Key characteristics of …
What is Normal Temperature and Pressure? Normal Temperature and Pressure (often abbreviated as NTP) are standard reference conditions used in various scientific and engineering contexts. The values for Normal Temperature and Pressure are typically defined as follows: When these values are combined, you get the standard conditions known as Normal Temperature and Pressure (NTP): NTP:T=0°C(273.15K),P=1atm(101.325kPa) …

Non-Flow Energy Equation in Thermodynamics The non-flow energy equation, also known as the General Energy Equation or the First Law of Thermodynamics in non-flow form, is a fundamental expression that describes the energy changes within a system. It is derived from the First Law of Thermodynamics and is applicable to both closed and open systems …
What is Boyle’s Law? Boyle’s Law is a fundamental principle in physics and thermodynamics that describes the relationship between the pressure and volume of a gas at constant temperature. This law is named after the Irish scientist Robert Boyle, who first stated it in 1662. Boyle’s Law Statement: “At constant temperature, the volume of a …
