  2. Thermochemical equation - Wikipedia

    en.wikipedia.org/wiki/Thermochemical_equation

    In thermochemistry, a thermochemical equation is a balanced chemical equation that represents the energy changes from a system to its surroundings. One such equation involves the enthalpy change, which is denoted with Δ H {\displaystyle \Delta H} In variable form, a thermochemical equation would appear similar to the following:

  3. Temperature - Wikipedia

    en.wikipedia.org/wiki/Temperature

    According to energy conservation and energy being a state function that does not change over a full cycle, the work from a heat engine over a full cycle is equal to the net heat, i.e. the sum of the heat put into the system at high temperature, q H > 0, and the waste heat given off at the low temperature, q C < 0.

  4. Laws of thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Laws_of_thermodynamics

    A particular consequence of this is that the total energy of an isolated system does not change. The concept of internal energy and its relationship to temperature. If a system has a definite temperature, then its total energy has three distinguishable components, termed kinetic energy (energy due to the motion of the system as a whole ...

    en.wikipedia.org/wiki/Chemical_reaction

    G: free energy, H: enthalpy, T: temperature, S: entropy, Δ: difference (change between original and product) Reactions can be exothermic , where Δ H is negative and energy is released. Typical examples of exothermic reactions are combustion , precipitation and crystallization , in which ordered solids are formed from disordered gaseous or ...

  7. Thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Thermodynamics

    Transfers of energy as work, or as heat, or of matter, between the system and the surroundings, take place through the walls, according to their respective permeabilities. Matter or energy that pass across the boundary so as to effect a change in the internal energy of the system need to be accounted for in the energy balance equation.

  8. Thermodynamic process - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_process

    The temperature-entropy conjugate pair is concerned with the transfer of energy, especially for a closed system. An isothermal process occurs at a constant temperature. An example would be a closed system immersed in and thermally connected with a large constant-temperature bath. Energy gained by the system, through work done on it, is lost to ...

  9. Calorimeter - Wikipedia

    en.wikipedia.org/wiki/Calorimeter

    Under these conditions the change in enthalpy equals the heat. Commercial calorimeters operate in a similar way. The semi-adiabatic (isoperibol) calorimeters measure temperature changes up to 10 −6 °C and account for heat loss through the walls of the reaction vessel to the environment, hence, semi-adiabatic. The reaction vessel is a dewar ...
