Gien the energy storages:
• Pumped Hydroelectric
,
• Flywheel
,
• Compressed Air
,
• Thermal Energy
Let's match the correct description to the type of energy storage.
• Pumped hydroelectric:
This is a type of hydroelectric storage. Here, the water is stored in an upper reservoir.
Therefore, the correct description is energy stored in water as gravitational potential energy.
• Flywheel
A flywheel is a device that stores rotational energy.
Therefore, the correct description is energy stored as kinetic rotational energy.
• Compressed Air:
For compressed air, the correct description is:
Energy is transferred to air that is forced under the ground at high pressure
• Thermal Energy:
This energy is possessed by an object due to the movement of particles in the object. It is produced when a temperature rise causes atoms and molecules to move faster.
Therefore, the correct description is Energy is used to cool water or make ice which can be used later for cooling when energy needs are high.
ANSWER:
Pumped Hydroelectric <==> Energy stored in water as gravitational potential energy.
Flywheel <==> Energy stored as kinetic rotational energy.
Compressed Air <==> Energy is transferred to air that is forced under the ground at high pressure
Thermal energy <==> Energy is used to cool water or make ice which can be used later for cooling when energy needs are high.
