Freezing is endothermic or exothermic
Did you know?
Freezing is exothermic. When water freezes, it gives off heat. That’s why you sometimes see ice cubes sitting in a puddle of water – the ice is melting and releasing heat, which keeps the surrounding water liquid. The same thing happens when you put a container of hot food in the freezer – the food gives off heat, … See more Freezing is a process that releases heat. This happens because when water freezes, the molecules have to move into a new shape. This new shape needs energy. In other … See more Freezing is typically considered to be an exothermic process, meaning that it releases heat. This is because when water freezes, the … See more An exothermic reaction is one that releases energy in the form of heat. The opposite of an exothermic reaction is an endothermicreaction, which absorbs heat. So why is freezing an … See more When water freezes, it releases heat into the surrounding environment. This process, known as exothermic freezing, occurs because the molecules of a substance are more ordered when they are in a solid state … See more WebIn Sam’s case, when ammonium nitrate was dissolved in water, the system absorbed heat from the surrounding, the flask, and thus the flask felt cold.This is an example of an endothermic reaction. In Julie’s case, when calcium chloride was dissolved in water, the system released heat into the surroundings, the flask, and thus the flask felt hot.. This is …
