VCE Chem

Fuel

a substance with stored energy that can be released easily for use

Non-renewable

used faster than they can be replaced

Biofuels

renewable energy formed from organic matter

Photosynthesis

Plant use O2 and CO2 + sunlight to make there food

Transesterification

Triglyceride + methanol = meltylester + glycerol

Renewability

Can be replenished naturally or through management

Sustainability

Meeting current needs without compromising future generations

Fossil fuels

Non-renewable energy formed from ancient matter

Respiration

The process of photosynthesis

Exothermic

Gives out heat

Endothermic

Takes in heat

Exothermic reaction

total chem energy of products is less than total chem energy of reactants = energy released

Endothermic reaction

total chem energy of products is greater than total chem energy of reactants = energy taken in

Activation energy

Starter to begin the reaction
