Why is thermal energy (heat) required to freeze ice into crystals?

A. heat must be released by the reactants and the products
B. Heat must be absorbed by the reactants and the products
C. Heat must be absorbed by the products in order to convert from the reactants.
4. Heat must be released by the products in order to convert from the reactants.

@DrBob222 If there are several links then you should know the answer, correct. Now did you give the answer, negative.So your response was useless!!!

The answer is C i just took the test! Make sure to read C though because the order of answers often change for those who are using this thread :)

@lani could you give the rest of the answers please?

Thank you! I hope I get the other ones correct too

The correct answer is B. Heat must be absorbed by the reactants and the products.

To understand why thermal energy is required to freeze ice into crystals, let's consider the basics of phase transitions.

When a substance undergoes a phase transition, such as freezing, it goes from one phase to another. In the case of water freezing, it changes from a liquid phase to a solid phase, forming ice crystals.

During this phase transition, energy is either absorbed or released. When a substance transitions from a lower energy phase (e.g., liquid) to a higher energy phase (e.g., solid), it needs to absorb energy in the form of heat to make this transition.

In the case of freezing water into ice crystals, heat needs to be absorbed by the reactants (water) and the products (ice) in order for the water molecules to slow down and arrange themselves into a solid, crystalline structure. This is why heat is required to freeze ice into crystals.

Look on Google. There are several links that talk about this. The idea is to add some heat to the system @ 0 degrees Celsius to give the H2O molecules enough energy to form the structure of ice.

Just a quick response. I told you HOW to get the answer and you preferred me to GIVE you the answer. No work on your part gives you nothing.
