Some refrigerants used in air conditioners have been associated with smog destruction of the ozone layer thermal pollution power failures

The correct answer is B. Destruction of the ozone layer

Explanation:

The ozone layer is the layer of the atmosphere that absorbs UV rays from the sun, indeed this layer absorbs around 98% of these rays. Due to this, the depletion of this layer can lead to skin cancer in humans and other negative consequences that are the result of UV rays. Unfortunately, in the last decades, this layer has been depleted or reduced mainly due to the use of chlorofluorocarbons that are substances found in aerosols and refrigerants including those used in air conditioners. Therefore, some refrigerants used in air conditioners have been associated with the destruction of the ozone layer.

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b
