Alecsey [184]

Answer:

C) ball rollinflown a hill

Explanation:

The question asks to  identify the endothermic process in the list of options. By way of elimination, we have;

A) condensation of water on a wind shield of a car

Condensation is an exothermic process. That is, heat is given out as the gases change into the liquid state of matter.

B) formation of copper

This is an exothermic process. Capture of electrons by a cation is always exothermic.

C) ball rollinflown a hill

This is the correct option. Energy is absorbed by the ball as it moves on the hill

D) formation of ice from liquid water

Freezing is an example of exothermic reaction. Heat is given off to the surroundings.

E) oxide from copper and oxygen

Formation of metal oxides and most reactions involving oxygen are exothermic reactions,

Why do you use the same amount of water for each shape of ice?
Fiesta28 [93]

Answer:

Ice is a solid form of liquid. Water simply expands when it freezes.

The same amount of water for each shape of ice because the melting  rate of ice depends on the surface area of each shape. So the same amount of water or volume with a large surface area will remain frozen for longer time.
