• False

Answer explanation

Since intensive properties do not depend on an amount of the substance, it is easy to identify a substance by characteristics such as density and smell.

True or False: It does not matter the specific conditions, such as temperature and pressure, under which observations are made because neither physical nor chemical properties depend on these conditions.

• True

• False

Answer explanation

We must identify the specific conditions because this can change the physical and chemical properties.
