Energy in chemical reactions and magnetism Flashcards
What is an endothermic reaction?
An endothermic reaction is a reaction that absorbs energy.
What occurs during an endothermic reaction?
In an endothermic reaction more energy is used to break the bonds than is released when new bonds are formed. The products feel colder than the reactants felt.
What is an exothermic reaction?
An exothermic reaction is a reaction that releases energy.
What occurs during an exothermic reaction?
In an exothermic reaction, more energy is released when new bonds are formed than is used to break old bonds. The products feel hotter than the reactants.
What is a magnetic field?
A magnetic field is any region where a magnetic substance will experience a magnetic force.
What is a ferromagnetic substance?
A substance one that is able to be turned into a permanent magnet.
