A student left a sealed jar of water outside her home. Water can be a solid, liquid, or gas. When she put it outside, the water was a solid. Twelve hours later, the water had changed phase and was a liquid. What happened to the water molecules?1. When the student left the jar outside, the molecules were moving around each other. Later, the molecules were moving in place. 2. When the student left the jar outside, the molecules were moving in place. Later, the molecules were moving around each other. 3. When the student left the jar outside, the molecules were moving away from each other. Later, the molecules were moving around each other. 4. When the student left the jar outside, the molecules were moving around each other. Later, the molecules were moving away from each other.

When the student left the jar outside, the molecules were moving in place. Later, the molecules were moving around each other

Explanation:

There are 4 states of matter:

They have the lowest kinetic energy and the particles do not move freely.

They have the high kinetic energy than solid and less than gases and the particles move freely.

They have the highest kinetic energy and the particles move freely.

As, the solid particles do not move freely. They move in their own place. The liquid particles are not closely packed. So, they move around the place.

Hence, when the student left the jar outside, the molecules were moving in place. Later, the molecules were moving around each other

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).
