Which of the following most likely happens when the number of particles of a gas decreases?

the pressure of the gas increases
the pressure of the gas remains same
the number of collisions of gas particles decreases
the number of collisions of gas particles stays the same

The correct option is C) The number of collisions of gas particles decreases

Explanation:

The molecules in a gas are not located close to each other as molecules in a solid or a liquid. The molecules in a gas have more energy. If we decrease the number of particles in a gas, then there will be reduced collisions as the molecules are already located further apart.

However, a decrease in the volume will affect the pressure of a gas, not the decrease in the number of gas particles.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
