Explanation:

1. consistency of getting the same measurement  → precision

Precision is refer to closeness of two or more measurements to each other.

2. closeness to actual measurement  → accuracy

Closeness of the measured value to standard or known value.

3. ratio of densities  → specific gravity

Specific gravity is defined as ratio of density of substance to the density of water.

4. the amount of matter in an object  →  mass

Amount of matter present in the body or an object is termed as Mass.

5. measure of pull of gravity  → weight

Weight of the object is product of mass of the body and acceleration due to gravity ; w = mg

6. mass divided by volume  → density

Density is defined as mass of substance present in uni volume of the substance.

7. Archimedes' Principle  → buoyancy

Buoyancy is the upthrust or an upward force exerted by the fluid in which object is immersed opposite to the weight of the immersed object.

8. How much space an object takes up → volume

Volume of the body or an object is the space occupied by it in medium.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

some sources quote the lethal dose, for an average 170lbs opiate-naive individual is between 75 and 375 mg
