1. choose the best answer.

engine oil is made of two or more atoms chemically combined. what type of substance is oil?
options: element, molecule, mixture

Explanation:

Question 2

Intensive properties don't depend on the amount of substance (e.g., density, temperature). Extensive depend on amount (e.g., mass, volume). Density of engine oil is intensive as it's the same regardless of the oil's quantity.

A mixture is a combination of two or more substances (not chemically combined). Engine oil is made of multiple components (atoms chemically combined into molecules, but oil as a substance is a mixture of different hydrocarbons/molecules). An element is a single type of atom, a molecule is a group of atoms, but oil is a mixture.

Answer:

intensive
