Energy Changes

We use hydrocarbons in many areas of our lives

Eg) glucose WHAT for WHAT

gasoline What and natural gas WHAT for WHAT

Glucose (C6H12O6) for CELLULAR RESPIRATION

Gasoline (octane C8H12) and natural gas (methane CH4) for FUEL

Energy stored in the WHAT of hydrocarbons originally comes from the WHAT

Energy stored in the CHEMICAL BONDS of hydrocarbons originally comes from the SUN

Ancient plants captured the energy of the sun during WHAT which undergoes intense WHAT and WHAT within the earths crust, resulting in the formation of fissile fuels like oil and natural gas

Ancient plants captured the energy of the sun during PHOTOSYNTHESIS which undergoes intense PRESSURE and HEAT within the earths crust, resulting in the formation of fissile fuels like oil and natural gas

What are the two fundamental types of energy

1. Kinetic energy (Ek)

2. Potential energy (Ep)

What is kinetic energy

The energy of MOTION (of particles)

What is potential energy

Energy that is STORED (in chemical bonds)

What is the system

What reacting or chemical reaction

What is surroundings

Reactants or everything outside or what’s changing in temperature
