Answer:
Global warming refers only to the Earth’s rising surface temperature, while climate change includes warming and the “side effects”
The chromosphere is the middle layer
Explanation:
Pressure = force / area
P = (68 kg × 9.8 m/s²) / (2 × (0.04 m)²)
P = 208,250 Pa
Converting to psi:
P = 208,250 N/m² × (0.225 lbf/N) × (0.0254 m/in)²
P = 30.2 psi
Answer: True
Explanation:
It should be noted that when refrigerant is added in vapor form to the operating refrigeration system, then the addition of the refrigerant should be to the low-pressure side of the refrigeration system.
Furthermore, when system pressures are lower than the pressure in the refrigerant tank as stated in the question, then the refrigerant can be added to both the high and low pressure sides of the system.
Therefore, the correct option is true.
A
most common source of phosphates in the soil is the weathering of the mineral apatite.
Explanation:
Apatite is a group of phosphate minerals like hydroxylapatite, fluorapatite, and chlorapatite. When apatite rocks weather, they release the phosphate minerals mainly in the form of PO₄ ³⁻ . These minerals become dissolved in water (hydrosphere), where they are readily available to plants and other organisms in the biosphere. The phosphates are taken up and used in biosynthesis. When these organisms die and become buried with sediments, the phosphate gets back to the lithosphere as sedimentary rock.
