can dissolving be endothermic process. I have a container with glucose(solid state) and added water and found the container getting colder. was wondering there is no reaction(just a physical process) and why would it absorb heat.
The answer to your question in general is yes.
There are many salts and compounds that are endothermic - they cool the solution when they dissolve. It also turns out that glucose is endothermic when it dissolves if this sheet i found is to be believed. Its not a strong effect but you made an accurate observation!
Endothermic salts can be quite cold. This is how home ice cream makers often work in fact - rock salt dissolves into the ice and makes it even colder than it started out to be. I believe that is how ice cream was made before refrigeration and ice storage arrived in the 19th century.
