When a cube of ice melts to form a puddle of water is it a physical or chemical change?
physical change
Is a car driving over a puddle a chemical or physical reaction?
When a car drives through a puddle of water, the change that takes place in the puddle is a physical change. Of course, chemical changes will take place in the engine of the car, but that's probably not what you are asking.
Is a puddle drying up in the sun a chemical or physical change?
It is a physical change, because it is still H20 when it evaporates and turns into vapor.
When a cube of ice melts to form a puddle of water is it a physical change?
Yes. No chemical change has taken place, only a physical change. It can be undone (liquid water can be re-frozen)
Is a puddle of water evaporating on a hot day a physical change?
Evaporation is a physical change.

Is water evaporating from a puddle a chemical change?
Evaporation of a pudle is a physical change,

Is a puddle of water evaprating into a rainstorm physical change?

Are melting and freezing physical changes are endothermic?
Freezing is an endothermic change. Freezing, for example a puddle of ice turn into an ice cube, the water is still the same thing but its just in a different form. The water is going into a different form, which is called endothermic. Hope this helped :)!
Is a puddle of water evoparating a chemical reaction?
Nope- physical change. It is still water, but chaged to a gas. It can be changed back to a liquid by condensing it from the air.
Which physical properties of the puddle change as the water evaporates?
The density of water is changed.
