When the pressure of gas doubles, the volume

When the pressure of gas is double the volume will decrease by the same factor.

Explanation:

According to the Bolye's law,

The pressure of given amount of gas at constant temperature and amount of gas is inversely proportional to its volume.

Mathematical relationship:

P∝1/V

P = K/V

PV = K

P₁V₁ = P₂V₂

P₁ =  initial pressure

V₁= initial volume

P₂= final pressure

V₂=final volume

So by increasing the pressure volume will decrease, or by decreasing the pressure volume will increase. The temperature and mole of gas are kept constant and pressure and volume changed by same factor.

the atomic mass is the bottom number on the element.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
