Magnetism, solubility, and malleability are physical properties of matter. What makes these properties different from
chemical properties?
A Physical properties relate to elements rather than compounds.
<
B Physical properties appear only after a chemical change occurs.
Physical properties can be observed without attempting to change the identity of the substance.
D Physical properties describe elements in the solid state rather than in the liquid or gas state.

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
