When water condenses on the side of your glass of cold lemonade is it a endothermic or exothermic reaction? and why?

Chemical reactions can be categorized as endothermic or exothermic reactions. The reactions that gain energy are endothermic, whereas the exothermic reactions evolve heat.

The glass of lemonade is gaining energy, thus, it is an endothermic reaction.

It can be explained as:

Thus, the system is gaining energy and is a type of endothermic reaction.

It is an endothermic process because the glas of lemonade is gaining energy.

Explanation:

The condensation of water is not a reaction, because the water is not changed into something else. We should call what’s happening a process.

The glass of lemonade is the system, and the rest of the universe is the surroundings.

When the water molecules in the atmosphere hit the sides of the cold glass, they give up some of their kinetic energy and condense into droplets of water.

The system is gaining energy from the surroundings, so the process is endothermic.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
