ASVAB General Science Practice Test 5

Question 1

Which type of electromagnetic radiation has the highest frequency?

Accepted Answer

Gamma rays

Answer

Gamma rays have the highest frequency (and shortest wavelength) in the electromagnetic spectrum, carrying the most energy per photon.

Question 2

What principle states that matter cannot be created or destroyed in a chemical reaction?

Accepted Answer

Law of conservation of mass

Question 4

In which direction does current flow in a conventional electric circuit?

Accepted Answer

From positive to negative terminal

Answer

By convention, current flows from the positive terminal through the external circuit to the negative terminal, opposite to the actual electron flow.

Question 5

What term describes the tendency of a liquid to resist an increase in its surface area?

Accepted Answer
