Question

Which of the following statements about freezing points is true?

a.The boiling point is the same for all substances

b.The freezing point of a substance is higher than its boiling point

c.The freezing point of a substance is lower than its boiling point

d.The freezing point of a substance can be the same as the boiling point

Answer 1

The boiling point of a substance is when it starts passing from the its liquid form to its gaseous form (evaporating), which requires high temperatures for most substances.

The freezing point of a substance is when it starts passing from its liquid form to its solid form (hardening), which requires rather low temperatures for most substances.

Given the above, your answer is:

`\boxed{\bf~C.~The~freezing~point~of~a~substance~is~lower~than~its~boiling~point}`
