As ice melts, it:

Quizplus · Accepted Answer

When ice melts, it requires heat energy to break the hydrogen bonds that hold the molecules together in a crystalline structure. This heat energy is absorbed from the surroundings, resulting in a decrease in temperature of the surroundings. Therefore, choice A is correct. 
Choice B is incorrect because as ice melts, it actually becomes more dense because the molecules are no longer arranged in a rigid structure. 
Choice C is incorrect because while water does have a property of cohesion, this property does not change as ice melts. 
Choice D is incorrect because the heat of vaporization refers to the amount of heat energy required to convert a liquid to a gas, and is not applicable to the melting of ice.
