Which of the following is a property of water? it can freeze very fast. it has low heat capacity. it exists in all three states on earth. it repels other water molecules.

It exists in three states .

It exists in all three states on earth.

Explanation:

Water is a tasteless, colorless and odourless liquid. On earth it exists in three states namely solid, liquid and gas.

Water as solid: The water in solid state exists as ice. Ice is frozen water. The molecules of water remains separate in ice. It exists in the glaciers or snow in some cold regions.

Water as liquid: The water in the liquid form is the most common form exists on earth. It is in the fluid form of water. It can be seen in the form of river, lakes, ponds, and oceans.

Water as gas: Water when heated it converts into gas. The gaseous form of water is called as water vapor. The water vapors remain in the earth atmosphere responsible for causing rain.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
