A sample of gas occupies 280 mL when the pressure is 560.00 mm Hg . If the temperature remains constant , what is the new pressure if the volume changes to 560.0 mL?

Answer : The new pressure if the volume changes to 560.0 mL is, 280 mmHg

Explanation :

According to the Boyle's, law, the pressure of the gas is inversely proportional to the volume of gas at constant temperature and moles of gas.

or,

where,

= initial pressure = 560.00 mmHg

= final pressure = ?

= initial volume = 280 mL

= final volume = 560.0 mL

Now put all the given values in the above formula, we get:

Therefore, the new pressure if the volume changes to 560.0 mL is, 280 mmHg

geosphere and hydrosphere.

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