IB Chemistry R1.1 Definitions
This page contains our IB Chemistry definitions for R1.1. By learning each one of these definitions, you will fully cover the content for IB Chemistry 'Enthalpy'.
calorimeter
A device that can measure an exothermic reaction's enthalpy change
endothermic reaction
A reaction that absorbs heat because the reactants have stronger bonds than the products
energy
The ability to move a unit force a unit distance, measured in joules. ie the amount of work done
enthalpy
The internal energy stored in molecules
exothermic reaction
A reaction that releases heat because the products have stronger bonds than the reactants
heat
It is the total kinetic energy of all particles in an object
specific heat capacity
The measure of how much energy a unit mass of a substance takes to be raised by 1K/1°C
temperature
It is the average kinetic energy of an object's particles
