The correct answer for the first question is liquid bromine. Liquids take the shape of its container but has a fixed volume. The correct answer for the second question is B. Water Vapor. Kinetic energy is a function of temperature, thus molecules at a higher temperature will have high Kinetic energy. In the choices given, water vapor has the highest temperature therefore it has the greatest kinetic energy.

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,
