The total kinetic energy of the particles in a system
the study of the movement of energy and heat.
or
Thermodynamics is the branch of physics concerned with the conversion of different energy forms.
•DeltaG (rxn) = DeltaG (pdts) - DeltaDG (rcts) •DeltaG°(rxn) = -R T ln K •
specific heat capacity of a substance is defined as the QUANITY OF HEAT REQUIRED to raise the temperature of 1 Kg of the substance through 1K ( kelvin ) .
however it obtained the unit of J/kg/k
The specific heat capacity is the energy required to raise the temperature of 1 kg of material by 1 degree Celsius.

Apex: The energy needed to change the temperature of a substance The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius.
Gas
Energy is transferred when molecules absorb electromagnetic waves.
The products becoming more spread out.
The energy needed to form the substance from its elements
If there is an increase in the number of gas molecules, then S > 0.
The reaction is exothermic.
The products becoming more ordered than the reactants
The energy needed to completely vaporize a mole of a liquid
the movement of energy and heat .
It tells if the reaction will process spontaneously or not
G = 0 kJ/mol
it is spontaneous at 500 k
The potential energy of the products is greater than the potential energy of the reactants.
The rocket might explode from the added pressure when the combustion reaction hits the air.
