Question 20 • Physical Science

A scientist is examining an unknown solid. Which procedure would most likely help determine a chemical property of the substance?

Answer
A
hitting it with a hammer to determine if it breaks or bends
B
heating it to find the temperature at which it melts
C
exposing it to a flame to see if it catches on fire
D
placing it in water to find out whether or not it dissolves

Explanation

A chemical property describes how a substance can change into a different substance. Whether the solid catches fire is its flammability, a chemical property, so exposing it to a flame is the best procedure. Breaking or bending, dissolving, and melting describe physical properties because they do not change the substance’s chemical identity.
