What is enthalpy?

Enthalpy is a property of a thermodynamic system, defined as the sum of the system's internal energy and the product of its pressure and volume. As a state function, enthalpy depends only on the final configuration of internal energy, pressure, and volume, not on the path taken to achieve it.

How to Calculate Enthalpy of the system?

Enthalpy of the system calculator uses Enthalpy=Number of Moles*Molar Specific Heat Capacity at Constant Pressure*Temperature Difference to calculate the Enthalpy, Enthalpy of the system is its thermodynamic property, defined as the sum of the system's internal energy and the product of its pressure and volume. It is a convenient state function standardly used in many measurements in chemical, biological, and physical systems at a constant pressure. The pressure-volume term expresses the work required to establish the system's physical dimensions, i.e. to make room for it by displacing its surroundings. As a state function, enthalpy depends only on the final configuration of internal energy, pressure, and volume, not on the path taken to achieve it. Enthalpy and is denoted by H symbol.

What is Enthalpy of the system?

Enthalpy of the system is its thermodynamic property, defined as the sum of the system's internal energy and the product of its pressure and volume. It is a convenient state function standardly used in many measurements in chemical, biological, and physical systems at a constant pressure. The pressure-volume term expresses the work required to establish the system's physical dimensions, i.e. to make room for it by displacing its surroundings. As a state function, enthalpy depends only on the final configuration of internal energy, pressure, and volume, not on the path taken to achieve it and is represented as H=n*C_p*dT or Enthalpy=Number of Moles*Molar Specific Heat Capacity at Constant Pressure*Temperature Difference. Temperature Difference is the measure of the hotness or the coldness of an object, Number of Moles is the amount of gas present in moles. 1 mole of gas weighs as much as its molecular weight and Molar Specific Heat Capacity at Constant Pressure , C_p ( of a gas ) is the amount of heat required to raise the temperature of 1 mol of the gas by 1 °C at the constant volume.
