M an unknown substance is cooled from 25 °c to 10 °c. the table below shows the state of the substance at different temperatures. time (minutes) temperature (degrees celsius) state of matter 0 25 liquid 2 23 liquid 4 18 6 18 8 18 10 15 solid 12 10 solid which statement is correct about the unknown substance? its freezing point is 23 °c. its freezing point is 18 °c. the substance sublimes at 23 °c. the substance exists as a gas at 18 °c.

The second statment is true and right. Hope this helps!!

Option (b) is the correct answer.

Explanation:

Freezing point is defined as the point at which liquid state of a substance changes into solid state.

So, in the given table it is shown that at temperature the substance is changing into solid state. Whereas at the substance is in liquid state.

Hence, will be the freezing point of the substance.

Thus, we can conclude that the statement its freezing point is , is correct about the unknown substance.
