How are real gases different from ideal gases? Real gases differ from ideal gases because in a real gas, and

Ideal gasses follow the ideal gas law, real gasses don't always.

Ideal gas law formula: PV=nRT

P = pressure

V = volume

n = number of moles

R = constant (changes depending on what units of pressure you use, atmospheres = 0.0821, millimeters of hydrogen = 62.4)

T = temperature

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
