Exothermic, more energy is release when bonds are made than is needed to break bonds between reactants. 10.What are the units for enthalpy change, ΔH kJ/mol Energy Changes in Chemical reactions for KS3 Science

Energy Stores. Energy can be stored in different ways, including:. kinetic (in a moving object); chemical (e.g. fuel + oxygen chemical bonds); thermal (in a warm object); nuclear (released through radioactive decay, fission or fusion); gravitational (due to the position of an object in a gravitational field height); magnetic (in two separated magnets that are attracting, or repelling)

Learn how energy can be stored and transferred with BBC Bitesize KS3 Science.

In transfer diagrams the boxes show the energy stores and the arrows show the energy transfers. For example, a transfer diagram for a child at the top of a slide may be: Gravitational energy stored in the child at the top of the slide is transferred as mechanical work done to speed up and to do work against friction. The result of this is a shift of energy from gravitational potential energy ...
