Question

A liquid substance at ordinary temperatures, such as water (H2O) or bromine (Br2) is heated sufficiently so that it evaporates. The substance would typically be said to be now in _______________ form.

Select one:

a.
rare


b.
vapor


c.
osmotic


d.
solid

Answer 1

b. vapor

Step-by-step explanation:

When a liquid substance is heated sufficiently, the energy from the heat causes the molecules to gain enough kinetic energy to break the intermolecular bonds and escape into the air as individual gas molecules. This process is called evaporation, and the substance in this gaseous form is known as a vapor. The term "vapor" refers to the gaseous form of a substance that was originally in a liquid state, and it typically refers to the mixture of gas molecules that are in constant motion and in contact with the air.
