Chemical Energy

Scientists measure Chemical Energy in units called:

• Kilojoules (kJ)

• Metres (m)

• Becquerels (Bq)

• Newtons (N)

What kind of energy is represented in the picture?

• Thermal

• Sound
• Nuclear

What type of energy can chemical transform into?

• Heat
• Light
• Electrical
• All of the above

Which of these is not a source of chemical energy?

• Spaghetti

• The Sun

• Battery

• Petrol

What factors determine the amount of chemical potential energy that an object has? 

• Mass of molecules and the position of chemical bonds
• Speed and mass of the molecules 
• The type of molecules present and their ability to catch fire
• Temperature of the molecules and position of the chemical bonds

Energy that is stored in chemical bonds based on the position of the bonds and is then released as thermal energy through chemical reactions is 

• thermal energy 
• chemical kinetic energy
