Answer the lab question (“What is the effect of temperature on the solubility of a solid in a liquid?”) with a hypothesis:

The solubility of a solid in a liquid increases with increase in temperature.

Explanation:

Solubility is defined as the amount of solute that can be dissolved in a given amount of solvent. For example in 100g of water at 25 degree Celsius 36 g of sodium chloride can be dissolved.

When a liquid is heated its kinetic energy increases and the particles start to vibrate or move. So when more amount of solute (sodium chloride) is added the solute particles finds its way into the solvent molecules (water) and hence the solubility increases.

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).
