The meaning of SIMPLE MACHINE is any of various elementary mechanisms formerly considered as the elements of which all machines are composed and including the lever, the wheel and axle, the pulley, the inclined plane, the wedge, and the screw.
The reaction also yields heat, which you can feel if you add enough vinegar and then touch the glass where the bubbling occurs. Reactions that produce heat are called “exothermic” reactions. Not all reactions are exothermic. Some reactions require heat in order to take place. These reactions ...

Chemical heating, using an exothermic oxidation reaction, offers a means to minimize cell phone battery usage [149,150]. (Electrical consumption of the cellphone is estimated to be 2% of total electrical power needed for electrical heating.) A thermos bottle type chip chemical heating system for ...
In contrast to the indirect assessment of metabolism by cell number measurements, isothermal microcalorimetry (IMC) records metabolic activity directly as the thermal metabolic power generated by microorganisms as a consequence of their overall exothermic biochemical reactions [14,15,16,17,18]. Therefore...
