Question

The volume of a fixed mass of gas at 760 mm Hg is
1500 cm? What is the pressure if the volume is reduced
to 1000 cm'at constant temperature?

Answer 1

Explanation:

The pressure exerted by a given mass of an ideal gas is inversely proportional to the volume it occupies if the temperature and amount of gas remain unchanged within a closed system.
