Total mass is the higher before reaction

Total mass is the same before and after a reaction

Total mass is the lower after a reaction

Energy used to make particles move more increasing the internal energy not temperature

Energy used to make/break bonds increasing the internal energy and temperature

Energy used to make/break bonds increasing the internal energy not temperature

Total kinetic and potential energy of particles in a system

Average kinetic energy of particles in a system

Average potential and kinetic energy of particles in a system

Total kinetic energy of particles in a system

it increases it

it decreases it

no effect

Change in energy (J) = mass (kg) x specific heat capacity (J/Kg°C) x change in temperature (°C)

∆ E = m c ∆ θ Change in energy (J) = mass (kg) x specific heat capacity (J/Kg°C) x change in temperature (°C)

∆ E = m c ∆ θ Change in energy (J) = mass (kg) x specific heat capacity (J/Kg°C) x change in temperature (°C)

mass (kg) = Change in energy (J) / (specific heat capacity (J/Kg°C) x change in temperature (°C) )

mass (kg) = specific heat capacity (J/Kg°C) x change in temperature (°C) / Change in energy (J)

mass (kg) = Change in energy (J) x specific heat capacity (J/Kg°C) / change in temperature (°C)
