Asyringe containing 1.75 ml of oxygen gas is cooled from 97.8 ∘c to 0.7 ∘c. what is the final volume vf of oxygen gas? (assume that the pressure is constant.)

Answer : The final volume of oxygen gas will be, 1.292 ml

Explanation :

Charles' Law : It is defined as the volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

or,

where,

= initial volume of oxygen gas = 1.75 ml

= final volume of oxygen gas = ?

= initial temperature of gas =

= final temperature of gas =

Now put all the given values in the above formula, we get the final volume of the oxygen gas.

Therefore, the final volume of oxygen gas will be, 1.292 ml

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
