True or false: the oscillating water column a device used to capture the power in waves operates by waves entering a shaft, compressing the air in the shaft, turning a turbine, which generates electricity

a. true
b. false

True

Explanation:

Oscillating water columns (OWC)

helps to harness energy from water and wind. Electricity is generated from the wave-driven rise and fall of water in a shaft.

The SHAFT-COLLECTED air is driven inside and upwards the top of the shaft due to the rising and falling water. Thus, powering the installed turbine, and GENERATING electricity.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m
