When the temperature is constant, the volume of a gas will decrease as the pressure decreases.

This statement is FALSE. Applying Boyle’s Law, when the temperature is held constant, Volume and Pressure will be inversely proportional to each other for a fixed amount of ideal gas, and this further means that as the volume increases, the pressure will decrease. It is easily referenced with the equation PV = k where P is for pressure, V for volume and k for the constant (temperature). Boyle’s law was named after Robert Boyle who was a chemist who published his work on 1662.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
