Calculate the energy required to evaporate the liquid using Equation I·t·Δϕ It, which yields the value H. Divide this value by the quantity of moles to obtain the molar enthalpy of vaporisation.
Joules are the units used to measure energy in the metric system. A joule is the unit of energy needed to raise an object weighing 1 kg 10 cm vertically or accelerate it from rest to a speed of 2 m/s. Energy can also be measured in various units, such as calories, BTUs, and kilowatt hours.
This is the fundamental energy unit of the metric system, or the International System of Units in a later, more thorough version (SI). In the end, the metre, kilogramme, and second are used to characterise it.
A moving object's kinetic energy, an object's potential energy, an object's elastic energy, chemical energy linked to chemical reactions, electromagnetic radiation's radiant energy, and the internal energy of a thermodynamic system are examples of common kinds of energy. Energy is constantly being consumed and expended by all living things.
