Test on Fundamental Concepts in General Science

Question 1: An atom is a group of two or more atoms held together.

A. Ano

B. Ne

Explanation: According to the study materials, 'Atoms' are 'the basic unit'. 'A group of two or more atoms held together' describes 'molecules', not atoms.

Question 2: Does a chemical change involve characteristics that describe an object's ability to become something?

A. Ano

B. Ne

Explanation: Chemical change refers to characteristics that describe something's ability to become something.

Question 3: Which of the following accurately lists the three primary states of matter according to the study materials?

A. Solid, Liquid, Plasma, Gas

B. Solid, Liquid, Gas

C. Compound, Mixture, Element

D. Mass, Volume, Density

Explanation: The study materials explicitly state: 'three primary studies of matter: Solid, liquid, gas.' and list 'States of matter: Solid, Liquid, Gas' under the 'What is Matter?' section.

Question 4: Which of the following is an example of a homogeneous mixture?

A. Salad

B. Air

C. Sand and water

D. Cereal with milk

Explanation: The study materials define homogeneous mixtures as being of the same kind or uniform in composition, and list examples such as salt water, air, and vinegar. Salad, sand and water, and cereal with milk are all listed as examples of heterogeneous mixtures.

Question 5: Students should be able to distinguish between homogeneous and heterogeneous mixtures.

A. Ano

B. Ne

Explanation: The study materials explicitly state that students should be able to 'Distinguish between homogeneous and heterogeneous mixtures'.
