The concentration of a solution can be expressed in(I ) milliliters per minute
(2) parts per million
(3) grams per Kelvin
(4) joules per gram

Answers

Answer:

(2) parts per million

Explanation:

Concentration of a solution can be expressed in terms of parts-per-million (ppm).

ppm is usually used in the context of measuring very small concentrations particularly the amount of contaminants. It represents 1 part of the contaminant in 100000 parts of the total.

It is expressed as:

1 ppm = 1 mg / L

1 ppm = 1 mg/ Kg
(I ) milliliters per minute
(2) parts per million
(3) grams per Kelvin
(4) joules per gram

What two factors affect the boiling point of water? A. Temperature and mass
B. Temperature and volume
C. Pressure and volume
D. Pressure and temperature

Answers

Answer:

D.  Pressure and temperature.

Explanation:

The answer is D because when water molecules (H2o) have heat and pressure added it will boil.  For exampe if your cooking pasta, you add water to your pan and when you add heat and put the lid of the pan it will boil.

Lightning rods are mounted on top of tall structures to protect them during thunderstorms. If lightning strikes, it will hit the rod and be directed to the ground through a wire, instead of passing through the structure. What type of substance should be used to make a lightning rod, and why?

Answers

Here we have to point out the necessary character of the substance needed which are used as lightning conductor.  

The substance should have the following properties:

High electricity carrying capacity and less resistant.

High melting point

The substance should have high electricity carrying capacity or the resistance is less so that the electricity generated during the lightning easily conducted to the ground  

The substance should have high melting point so that during lightning the generated high temperature cannot disrupt the material.

Answer:The lightning rod should be constructed of a metal, which is an inorganic substance.

Metals are good conductors of electricity.
