☆☆☆☆☆To put it in simple terms, all of the energy that would normally increase the temperature of the object, is being used to convert the object from one phase to another.
Once the object has completely changed to the new phase, the energy is not needed for phase change and raises the temperature of the object.
Because energy is being used to overcome intermolecular forces(apex)
It is multiplied by 2 if the intermediate reaction is multiplied by 2
Liters liquid 1000ml/1L g/ml mol/g Hfusion
1kJ 1/Hfusion g/mol ml/g liquid
Reactions that increase the moles of gas will increase in entropy.
G is always negative when H is negative and S is positive.
Entropy increases.
Kinetics
2.5 g 1 mol/18.02 g (-285.83) kJ/mol
The enthalpy of a reaction does not depend on the intermediate reactions.
That flame is the source of heat for the hot air in the hot air balloon.
Force
Air
(Explanation): water has a high specific heat capacity, but it can boil. stone (😂) also is a good thermal insulator, but it can get really hot. Metal is a very good thermal conductor, so it is definitely not that. Therefore, air is the best (its also really hard to boil).
