Answer:
c) predicting the boiling point of a liquid,
Step-by-step explanation:
a) predicting the properties of an element based on its placement on the periodic table
b) writing noble gas configurations for an element
c) predicting the boiling point of a liquid, given its pressure
d) predicting the acidic or basic nature of a substance based on its pH
Options a, b, and d are clearly based on the chemical nature of an element which is based on the electronic configuration.
But option c however is based on observing a change in physical state, which is primarily based on a understanding of physics.
