Thermochemistry is the application of thermodynamics to chemistry. Thermochemistry is used to predict the energy exchanges that occur in the following processes: 1.<Tab/>chemical reactions 2.<Tab/>phase changes such as boiling and melting 3.<Tab/>the formation of solutions Thermochemistry is primarily concerned with the following state functions defined in thermodynamics: *<Tab/>Internal energy (U) *<Tab/>…showed first 75 words of 731 total…

A gas becomes warmer if and only if the average kinetic energy of the gas particles increases. Heat, when it raises the temperature of a system, produces an increase in the speed with which the particles of the system move, as shown in the figure below.
