Endothermic and exothermic reactions

[Aslandawiz]

Hi,

I came across a question where it said adding sugar to water will decrease the temperature of the water and I have to explain why. I understand that it is due to the bonding with the water and sugar and my reason for that is this:

 

-When sugar formed a bond with water, the bonding releases energy in the form of heat. Therefore, the temperature of the water decreases for the heat is transferred to the surroundings.

 

But it appears that I am wrong, for I searched google and it appears that surrounding is part of the "temperature" of the water. Does that mean that the answer to the question is:

 

-When the heat broke the bonds between water and hydrogen atoms so that the sugar could bond with the water, the heat from the surroundings and the water is converted into energy that is used to break the bond. Therefore, the temperature from the surroundings and water is decreased for it is used to break the bond.

 

Which one is correct? Or am I entirely wrong?

So forming bonds releases energy. Are you breaking any bonds that would require energy from the water?
