, Enthalpy is measured as the sum of internal energy and the product of volume and pressure. It is a state function that has the dimension same as that of energy that is joule in S.I and ergs in c.g.s. Its value depends on the pressure, composition, and temperature of the system....

The term Enthalpy in a thermodynamic system represents its total internal energy. When ever a work is done by the system, there is a decrease in its entropy and when ever some work is done on the system, energy is gained and thus its entropy increases. It keeps on changing whenever a sy...
The enthalpy change is independent upon the path. There are also many other terms that are state function, such as internal energy, entropy etc.Answer and Explanation: When a reaction forms products, either it is given heat (enthalpy change = +ve) or releases heat (enthalpy change = -ve)....
What's the difference between heat capacity and enthalpy change? Explain the difference between heat and temperature. What is the difference in temperature changes in terms of the specific heat capacities of lead and water? What is heat? How does heat differ from thermal energy? Under what condi...
Is the process of liquid water being converted to ice endothermic or exothermic? What happens when a solid is dissolved into a liquid? What is enthalpy of steam? Which of the following releases the greatest amount of energy? a. steam condensing to water b. water freezing to ice c. ice ...
In equation 4, H is the enthalpy, and F is the free energy (also known as the Gibb's free energy). Likewise, H and F are incremental variations of those quantities, and S is an incremental change in the entropy of the chemical system, in the event of a chemical reaction. ...
Energy values, as you know, are all relative, and must be defined on a scale that is completely arbitrary; there is no such thing as the absolute energy of a substance, so we can arbitrarily define the enthalpy or internal energy of an element in its most stable form at 298K and 1 ...

have special concerns about the heat capacity and other quantifiable physical parameters related to matter in this state. One example isenthalpy, which is a measure of the internal heat of a closed system. It is the sum of the energy of the system plus the product of its pressure and volume...
