It is the lowest at low temperature

Answer from: lucylooe11

This question includes four answer choices: A) it is the lowest at low temperature B) it increases at low temperature C) it is the same at all temperature D) is it the lowest at high temperature The right statement is the option A) it is the lowest at low temperature. The Molecular Kinetic Theory describes the behavior of the gases in terms of the motion of the particles. It makes several assumptions about the size, the motion and the kinetic energy of the particles (molecules). Given that the kinetic energy, KE, is KE = m * v^2 / 2 and that the speed of the particles is higher at higher temperatures and lower to lower temperatures, you conclude the the kinetic energy of a molecule is the lowest at low temperature, i.e the option A).

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).
