Match the term with the definition. match term definition compressibility a) measure of how much heat is given off when a substance is burned flammability b) the ability of a substance to damage or harm an organism heat of combustion c) measure of how much the volume of matter can decrease under pressure toxicity d) how easily a substance can be set on fire

Explanation:

When pressure is applied on a substance and then reduction in size of the substance is known as compressibility.

Flammability is defined as the ability of a substance to readily catch fire.

A substance that causes harm or damage to an organism is known as toxic substance.

When one mole of a substance is heated then the energy released is known as heat of combustion.

Therefore, given definitions are matched with the definition as follows.

Compressibility - C) Measure of how much the volume of matter can decrease under pressure. Flammability - D) How easily a substance can be set on fire.Heat of combustion - A) Measure of how much heat is given off when a substance is burned. Toxicity - B) The ability of a substance to damage or harm an organism.

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.
