Which phrase best describes heat? a. the energy that an object has as a result of its temperature b. the average translational kinetic energy of the particles in an object c. the energy transferred between objects at different temperatures d. the total amount of energy possessed by the particles in an object

Option (C) is the correct answer.

Explanation:

When we provide heat to a substance then its molecules start to vibrate more rapidly. As a result, molecules gain kinetic energy and collide more rapidly.

Hence, this energy is given off in the form of heat.

So, when two objects with different temperatures are placed adjacently in contact with each other then heat will transfer from hotter object to colder object.

Thus, we can conclude that the phrase energy transferred between objects at different temperatures best describes heat.

c, liquids evaporate, creating a gas

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).
