GED Science Test #5

Question 1

What is the most likely pH of a solution with a lot of hydroxide ions (OH-) but not a lot of hydrogen ions (H+)?

Accepted Answer

9

Answer

A base is a solution in which there are more hydroxide ions than hydrogen ions, and bases have a pH greater than 7, hence the only answer is 9.

Question 2

Which of the supplied response options best describes the following statement?
Is there an inverse relationship between the volume and pressure of gas for a given mass and constant temperature?

Accepted Answer

Boyle's Law

Answer

For a fixed mass and temperature, Boyle's law states that pressure and volume are inversely related: PV = c, where c = constant.

Question 3

Nora prepares soup by stirring several spices into a pot of boiling water until they are totally dissolved. She then adds a variety of chopped vegetables. What's the solute in her concoction?

Accepted Answer

Spices

Answer

A material that is dissolved in another substance is referred to as a solute. The solute in this case is the spices.

Question 4

If "L" stands for tallness and "l" stands for shortness, which of the following best reflects the attribute Ll?

Accepted Answer

Heterozygous genotype and tall phenotype

Answer

The characteristic Ll characterizes a person's genotype or the qualities associated with their genes. Because it has both a dominant and recessive gene, it is heterozygous. Because the dominant gene L for tallness is phenotypic of the person or the physical manifestation of the genes they carry, tallness is the person's phenotype or the physical expression of the genes they carry.

Question 5

What law governs the interaction of two charged particles?

Accepted Answer

Coulomb's law

Answer

Coulomb's law describes the electric force between two charged particles. It claims that opposite charges attract and like charges repel one other and that the greater the distance between them, the less force they will exert on each other.
