Which statement concerning energy change is false?
- A
Electrical energy is produced by the reaction in a battery
- B
Light energy is absorbed during photosynthesis
- C
Light energy is produced when Methane burns in Oxygen
- D
Heat energy is liberated when Sodium reacts with water.
The false statement concerning energy change is:
C. Light energy is produced when Methane burns in Oxygen.
When methane (CH4) burns in oxygen (O2), the primary forms of energy released are heat energy and, to a lesser extent, light energy. Therefore, statement C is false.
Chemical energy is converted into electrical energy in a battery.
Plants absorb light energy to carry out photosynthesis
Methane releases its chemical energy by undergoing hydrocarbon combustion.
The reaction of sodium metal with water is highly endothermic therefore, heat energy is absorbed during this reaction.
