An investigation comparing how the two compounds dissolve in water.
b
An investigation comparing the color of two compounds at room temperature.
c
An investigation comparing which of the two compounds is combustible.
d
An investigation comparing the melting points of two compounds.

Answer 1

c

Combustibility is a chemical property because it involves a substance undergoing a chemical change (burning). The others (solubility, color at room temp, melting point) are physical properties.
