Question

which statement(s) is/are true for a liquid that has reached its boiling point?
select all that apply
a bubbles can form.
b bubbles cannot form.
c vapor pressure = atmospheric pressure
d vapor pressure < atmospheric pressure

Explanation:

• When a liquid reaches its boiling point, vapor pressure equals atmospheric pressure. This allows bubbles (which are pockets of vapor) to form as the liquid can convert to gas throughout the bulk of the liquid.
• If vapor pressure was less than atmospheric pressure (as in non - boiling situations for a liquid in an open container), bubbles cannot form because the external pressure would collapse any incipient vapor pockets.

Answer:

A. Bubbles can form, C. vapor pressure = atmospheric pressure
