What is Enthalpy? - Enthalpy in the thermodynamic system. Know about changes in enthalpy during an endothermic and exothermic reaction. Learn in detail about Enthalpy in detail at BYJU'S.
We can rewrite as H1– H2= ΔH = q Where ΔH represents the increase in the enthalpy of a system when it changes from state 1 to state 2. Like internal energy, enthalpy is also an extensive property as well as a state function. The absolute value of enthalpy cannot be determined. Ho...

The late Frank Lambert contributed greatly to debunking the "entropy = disorder" myth in chemistry education. See his articles Entropy is Simple, and Teaching Entropy. Entropy is still described, particularly in older textbooks, as a measure of disorder. In a narrow technical sense this is correc...
What is the change in entropy when a) 100 g of ice is melted at 0 degree C b) 100 g of water is vaporized to 100 degree C Use the values for each step to calculate the change in entropy when 100 g of What would you expect f...

In chemistry, a calorimeter is defined as the device which is used to measure the amount of heat flow (amount of heat released or amount of heat absorbed) in the chemical reaction. The calorimeter is also used to measure the heat capacity....
What is enthalpy?Is enthalpy the action of when you burn a compound in order to find the amount of heat or is enthalpy just the actual heat that is produced? What is enthalpy a measure of? 2.98 g of a gas (20.6 g mol^{-1}) was dissolved in liquid water in a calorimeter with a...
The real interest for the chemist, is to predict whether or not a given chemical reaction will go. 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 ...
Another way to state this is that the change in entropy (ΔS) equals the change in heat (ΔQ) divided by the absolute temperature (T): ΔS=ΔQ/T Entropy and Internal Energy In physical chemistry and thermodynamics, one of the most useful equations relates entropy to the internal energy ...
