Question 20
which of the following increases the solubility of a gas?
a)increased temperature
b)decreased pressure
c)decreased temperature
d)shaking

The solubility is increased by C) decreased temperature.

As the temperature builds, the solvency of a gas decline and decreased temperature leads to high solubility of gas. It is because for solution with low temperature, high amount of gas is available whereas for solution with high temperature less gas is available.

The explanation behind this gas dissolvability association with temperature is fundamentally the same as the explanation that vapor weight increments with temperature. Expanded temperature causes an expansion in motor vitality. The higher dynamic vitality causes more movement in particles which break intermolecular bonds and getaway from arrangement.

d. organisms have cells with different shapes and functions.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
