lesson 5.3 pg:no 74
Exothermic reaction
Exo=exit , Thermic=heat .
These reactions give out energy in several ways like .
Heat , Light , Sound , Electricity .
It is also called down hill reaction because product have less energy than reaction .
Endothermic reaction
Endo=to go in , Thermic=heat .
These reaction take in energy in many ways like .
Ice melting .
Photosynthesis .
It is also called a up hill reaction because reaction have less energy than products .
Change spelling of redaction to reduction.
